Assume the same numbers for area and temperature as in the previous problem and calculate the btus per second lost through the plywood. the thermal conductivity of plywood is 0.13 j/smk 7. a large window is broken and a 0.15m thick piece of plywood is used to keep the cold 5pts 8. from the nuclear power. net website, nuclear steam engines operate between 275.6°c and 415°c. a power plant may produce 8000mj each second while wasting 16,000mj of heat through exhaust, inefficient energy transfer, friction, etc. a)how much energy must be produced by the nuclear steam plant to power this engine? b)what is the ideal efficiency of any heat engine operating at these temperatures? e) what is the actual efficiency of the given typical nuclear power plant numbers provided? 10 pts an evaporative cooler works by forcing hot desert air at 6% humidity through a wet sponge where the air picks up moisture and cools down by giving its heat energy to the liquid water to make it a gas. these coolers operate at input temperatures of 110°f and produce output air temperatures of 65 9, a) what would the maximum coefficient of performance be for an air conditioner operating at these temperatures? b) a house with a 1 ton rated air conditioner removes 1.2573 x 10" j/hr from a building. to 2 digits, calculate the input electrical energy in j/s that this would require in the arizona desert using the above cop you calculated.
