Question

Why does getting into a bath at 105 degree F feel warmer than showering under a spray of water at 105 degree F? there is a lot of radiation heat transfer in a bath the thermal conductivity of water is much lower in the shower there is a greater temperature difference between the water and your skin in a bath. more (nearly all) of your skin's surface area is exposed to bath water compared to the shower Polyurethane foam is a very good insulating material, and has a thermal conductivity of around 0.020 W/m-K. What is the thermal conductivity of polyurethane foam in English units, Btu/ft-h-degree F? (You'll need to look up unit conversions; 1 K. = 1.8 degree F for a AT temperature change). 0.0021 Btu/ft-h-degree F 0.012 Btu/ft-h-degree F 0.25 Btu/ft-h-degree F 0.98 Btu/fl-h-degree F 23.4 Btu/ft-h-degree F A steam radiator is used to heat a room in the winter. If the surface of the radiator is 105 degree C (378 K), and the radiator has an emissivity, epsilon, of 0.92, what is the heat flux (q/A) to the surrounding cold room (T_sur = 291 K)? 691 W/m^2 1624 W/m^2 25, 660 W/m^2 1.2 * 10^10 W/m^2

Explanation / Answer

7. Answer-D

Reason: During shower the water droplets which fall on our body has higher heat trasfer beacuse of high surface area of the drops. because of high heat transfer the temperature of body lose more heat.

when compared to bath at the same temperature as shower water, the heat transfer is less and the body doesnt lose much heat therefore our body feels a bit warmer. but after shower our body loses most of the heat and hence we might feel a bit shivering.
