What is the physical basis for existence of a critical insulation radius?
The general thinking is that with the increase in thickness of insulation around the system(say a pipe) the heat loss will always reduce.This is true only up to a certain radius of the insulation called the critical insulation radius.After this radius any increase in the thickness would in fact increase the heat loss.This happens because there are two phenomena taking place here viz. conduction and convection.Conductive resistance is dx/k i.e. thickness/conductivity with increase in thickness the conductive resistance increases hence heat loss decreases.Convective resistance is 1/hA,now beyond the critical radius the increase in conductive resistance is offset by the reduction in convective resistance.This is because with increasing radius one has also achieved a greater heat transfer area as A=2*pi*r*l.

What are the various uses for polyethylene glycol?

What is the usage of diethyl malonate in organic synthesis?
Diethyl malonate, a colourless, fragrant liquid boiling at 199 C, is prepared by the reaction of monochloroacetatic acid with methanol, carbon monoxide or by the reaction cyanoacetic acid (the half nitriled-malonic acid) with ethyl alcohol. Diethyl malonate is an important intermediate in syntheses of vitamins B1 and B6, barbiturates, non-steroidal anti-inflammatory agents, other numerous pharmaceuticals, agrochemicals and flavors & fragrances compounds.

What is the function of subcutaneous layers?
The function of the subcutaneous layer is insulation and mechanical protection.
How does one install foam pipe insulation?
The installation of pipe insulation is fairly easy. Pipes that are not covered seem to sweat, or they can freeze in the winter. Find pipe insulation the size in diameter of the pipe. Slit a cut down one side and place over the pipe.
How do you make yourself stop itching from insulation?
Anti-itch cream like Lanacaine, Hydrocortisone.
Explain the various ways in which the skin can serve to regulate an organism's temperature?
The skin helps regulate temperature through processes like sweating, where sweat evaporates to cool the body, and vasoconstriction or vasodilation to retain or release heat respectively. Hair on the skin can also trap heat close to the body or help cool by creating a layer of air for insulation. Additionally, shivering can generate heat in response to cold temperatures.
You often sweat through your deodorant -- Is there any way to fix this?
All a deodorant does is put a masking smell in the areas you apply it to. If you want to help minimise sweating (aka perspiration) use an anti-perspirant. A deodorant is just perfume. An anti-perspirant puts down a layer that is harder to sweat through.
Why do people wear heavy clothes in the desert?
Primarily as insulation from the desert heat. I believe also that the cotton cloth wicks away sweat and helps cool the body.
Should athletes wear deodorant during games?
No, they shouldn't. For one thing, it blocks their sweat glands. Even if it just says "deodorant," rather than anti-perspirant, it still blocks the the sweat glands.
Which is the best product on sweat stains?
Sweat stains should best be avoided then getting into a practice of removing. If you sweat too much, try and use good anti perspirants. Wash armpits clean daily twice. This manage excessive sweating and also any bacterial action. Hence if you are not clear on how to get rid of sweat stains, better use these methods.
What is the difference between anti-perspirant and deodorant?
Antiperspirant prevents perspiration (sweating). Deodorant prevents odor.Antiperspirants contain fragrance, but they also contain chemical compounds that block the pores to stop the discharge of perspiration. No sweat, no odor.Deodorant allows the release of perspiration, but prevents odor by combating it with antiseptic agents, which kill odor-causing bacteria.
