The Travelers’ Temperature Predicaments (2)

Temperature measurement is very important to a whole range of areas and activities: science, scientific research, manufacturing, medicine and travel. Many European, Asian and African businessmen and tourists often travel to the USA and UK. These countries have not adopted the use of the modern metric system of measurement i.e. the SI system.

The accepted base SI unit of temperature is the Kelvin. A change of 1K is the same as 1 degree Celsius. As the degree Celsius is a convenient, easy to grasp in every – day – life metric unit, therefore both units are used in parallel. The Kelvin is used by scientists and engineers and the degree Celsius by everybody else worldwide. There are however, two prominent exceptions: the USA and UK who commonly use the Fahrenheit scale.

Daniel, Gabriel Fahrenheit, a German physicist was born in 1686 in Gdansk, Poland. The concept of the thermometer for measuring temperature changes is credited to Galileo. Fahrenheit is known for inventing the alcohol and mercury thermometers. His temperature scale is based on affixing 32º for melting point of ice and 212º for the boiling point of water under normal atmospheric pressure. The interval between two affixed points is being divided into 180 equal parts (the degrees Fahrenheit). The Fahrenheit scale was generally in use by English speaking countries up until 1970.
Travelers to the USA and UK are often faced with the problem of how to efficiently convert the temperature in the degree Fahrenheit to the temperature expressed in the degrees Celsius without making a mistake and with a sufficient approximation.

The conversion formula “Fahrenheit to Celsius” is:

ºC = 5/9 (ºF – 32º); read:

“In order to express the temperature in the degrees Celsius, I need to divide 5 by 9 and the result multiply by the temperature in Fahrenheit lowered by 32º”.

Quite awkward, isn’t it?

A much simpler way to remember and easier method to do mentally is to memorise the four following steps:

ºF→→→ºC : “Subtract 32, divide by 2, add 10% ( or 1/10) of the result and add 1% of the total”.

Let us see how it works:

E.g. 1: 98 ºF (your normal body temperature) →→→66 →→→33 →→→36.3 →→→36.7 ºC (rounded off to one decimal place).

E.g. 2: 102 ºF (your possible body temperature) →→→70→→→35→→→38.5→→→38.9 ºC

(High, pay a visit to the doctor!).

E.g. 3: 68 ºF (pleasant, refreshing outdoor temperature)→→→36→→→18→→→19.8→→→20 ºC

If you in a good mood, hum these four steps before the travel: “su-di-a-a”, “su-di-a-a”, “su-di-a-a”…!

Have a nice trip and keep warm!

If so, you will be able to find the answer to the following puzzle:

FORGETFULNESS

A student solving a problem on transfer of heat found a correct temperature change. However, he presented the answer without a unit. As it turned out, it did not matter whether he gave the temperature in the degrees Fahrenheit or the degrees Celsius. The answer remained the same. What temperature was it?

Common Measurements of RV Trailers

There are different kinds of RV trailers in the market. These trailers are manufactured and assembled by different vehicle lines. However, they will tend to have measurements that are somewhat standard and universal in outlook. As with other kinds of vehicles, this is one of the important aspects of RV trailers. Still, you will be very well advised to note the measurement specifications of the trailer you are looking to procure before you even draw out your check book. This is mainly because you certainly will not want a trailer that is too small for your possessions or the people who will travel in it.

For one, the common overall length of most travel trailers does not exceed 12. 5 meters. Of course, most of us think that this particular measurement is not important. However, you will notice that it is one of the most primal things you will want to consider before you put a recreational vehicle on hold.

In the same way, the overall width of your prospective travel trailer should have a measurement that does not exceed 2.6 meters. This adds up to 8 feet and 6 inches. This measurement is even more important since you will certainly not want to get your recreational vehicle trailer through gateways or narrow passes.

To note is that this width is actually a total of that distance measured from the center line of the vehicle to all outermost projections found on each of its side. This includes water connections and door handles. This particular measurement of travel trailers comes in handy when you are looking to fold your recreational vehicle or to stow it away ready for transit.

There are many things you need to note about the measurements of RV trailers. For one, there are different kinds of these trailers and you will have to look at each kind to determine the best one for your particular case. For instance, there are fold able camping trailers. In the same way, you may decide to opt for travel trailers. There are also motor- homes, truck campers with slide- in facilities and trailers featuring a fifth wheel.

Remember that fifth wheel recreational vehicle travel trailers will normally have a standard measurement of 11. 3 meters (this translates to some 37 feet). The measurement is commonly taken from front of its main body to the extremity. This is actually measured at the basic front line of these trailers.

The measurements of RV trailers may seem trivial. However, once you put your recreational vehicle trailer into use, you will discover the importance of these measurements. For one, most travel trailers will tend to be towed or transported. You can be certain that it is impossible to tow or transport a trailer that is too large. In the same way, it is impossible to live in an RV trailer that is too small.

To conclude, RV trailers are very important if you are looking to travel with your home and not have to depend on hospitality to enjoy an excursion with family or friends. In fact, once you add such a trailer to your garage, you will discover that it becomes cheaper to travel and take vacations.

Travel Trailer Covers – Buying the Right One

With all of the excitement of purchasing a new camper, the thought of protecting it when not in use may be overlooked. Since your camper may be such a large investment, you should do everything you can protect it. Travel trailer covers are probably the least expensive way to protect you camper. From the damaging UV rays from the sun, dirt and dust, heavy rain fall and freezing winter weather (for some of us), having your camper covered with a quality RV cover is one way you can ensure your camper is protected and extended its life.

When you’re shopping for RV trailer covers, it is important to know the right size to buy to make sure you have a good fit. Just because your owner’s manual says that it is a 29 foot camper doesn’t mean that it actually is! You will want to measure the camper for yourself. When you go to measure your camper you are going to measure from end to end. Start at the furthest point of the camper at the rear of your camper. Be sure to include the ladder, bumper or spare tire. Measure to the front of the camper but do not include the propane tanks or hitching. If you have a roof air, be sure to add an addition one foot to the final measurement. Now that you have your measurements, you are ready to start your search for travel trailer covers.

One important feature to consider is your climate. If you climate is damp, it is especially important to consider travel trailer covers that “breath”. Tyvek Travel Trailer Covers are made with Polypropylene sides to ensure maximum breathability and it virtually eliminates mold and mildew. Its two layer Tyvek top panel resists water and allows trapped moisture to evaporate from within. UV protection is also very important in all climates.

Other features to consider are the travel trailer covers straps and buckle attachments to prevent billowing on windy days, reinforced corners to resist tears and heavy duty zipper “doors” for easy access to your travel trailer while it is covered. Many brands of travel trailer covers are being designed with many zippers to allow access to your camper no matter where the entrance door is located.

Since travel trailer covers will be exposed to the elements, they will weaken over time. You will want to find a cover that has a good warranty. These covers are going to protect your investment so you will want to make sure that it is of good quality and will last for many seasons. It is important to know how long the warranty is and what the warranty covers.

When you have decided on the brand and type of travel trailer covers that you are going to purchase, you will have to choose the cover size. If you are sure that you have measured correctly, now you will need to locate the size that is closest to your measurement. RV covers are made to fit a size range like 24’1″ to 26″. Find the range that is closest to you measurement. It is better for it to be a little bigger than it is for it to be a little too small. If it is too small, you will have to stretch the material to fit with can cause unnecessary strain to the cover. Besides, most of the better made travel trailer covers allow you to tighten up the corners and edges to make for a better fit.

You have made a wise choice in considering protecting your camper with a cover. Whether you are storing your camper indoors or outdoors, travel trailer covers will keep you camper cleaner and in better condition which will extend the life of your camper as well as keeping the resale value higher if you should choose to sell or trade in your travel trailer.
