A cheese ripening room which, has a total surface area of A = 25.0m2, has to ensure that the inside temperature does not exceed 11.0°C at all times. If the maximum outside temperature is 35.0°C and the cheese ripening room has an air conditioner which provides 125 kW of cooling, calculate the how thi ck the wooden walls would need to bein mm, in order to ensure the inside temperature do es not go above 11.0°C. Assume that the thermal W conductivity, k of wood is 0.0800 Assume that the entire cheese ripening room is m.C made of wood (including ceiling and floor) and ignore any losses through the door as it remains closed most of the time and is well sealed. Given: P = KA(Tinside –Toutside ) L
The storage of radioactive waste is an important problem in the nuclear industry. One problem that scientists must take into account is volumetric expansion. Consider a 25.0 gallon metal canister of diameter 22.0 inches filled with a radioactive waste possessing a coefficient of volume expansion of 9.60 x 10-4 ('C)-'. This canister will be filled at room temperature (23.0 °C) and lowered deep into the Earth (where temperatures can reach 155 °C) for storage. If the coefficient of volume expansion of the metal is 4.10 x 10-5 (*C)-', how much waste will spill over the top if the lid becomes looOse? amount of waste: gallons
A brass rod is 40.1 cm long and an aluminum rod is 79.3 cm long when both rods are at an initialtemperature of 0°C. The rods are placed in line with a gap of 0.60 cm between them, as shown in the figure. The distance between the far ends of the rods is maintained at 120.0 cm throughout. The temperature of both rods is raised until the two rods are barely in contact. The coefficientsof linear expansion of brass and aluminum are 2.0 × 10^-5 K^-1 and 2.4 × 10^-5 K^-1, respectively. What is the temperature at which contact of the rods barely occurs?
