What is the rate of heat transfer by radiation, with an unclothed person standing in a dark room whose ambient temperature is 22.0ºc . the person has a normal skin temperature of 33.0ºc and a surface area of 1.50 m2. the emissivity of skin is 0.97 in the infrared, where the radiation takes place.
Answers: 2
W
= Temperature of the room = 22.0 °C = 22 + 273 = 295 K 
= Temperature of the skin = 33.0 °C = 33 + 273 = 306 K
= Surface area = 1.50 m²
= emissivity = 0.97 
= Stefan's constant = 5.67 x 10⁻⁸ Wm⁻² K⁻⁴

An insulated 40 ft^3 rigid tank contains air at 50 psia and 120°f. a valve connected to the tank is now opened, and air is allowed to escape until the pressure inside drops to 25 psia. the air temperature during this process is kept constant by an electric resistance heater placed in the tank. determine the electrical work done during this process.
