Multiple-Concept Example 6 provides a review of the concepts that play roles here. An engine has an efficiency of 64% and produces 5500 J of work. What are the input heat and rejected heat? input heat = 8600 J, rejected heat = 3100 J input heat = 2000 J, rejected heat = 3500 J

E14 An engineer designs a heat engine using flat-plate solar collectors. The collector deliver heat at 72°C and the engine releases heat to the surroundings at 33°C. What is the maximum possible efficiency of this engine?

The ice maker inside a refrigerator makes ice cubes at 0.0°C from water that is at 14.2°C when it first enters the ice maker. If this machine is rated at 184 W and has a 3.26 coefficient of performance, what is the maximum amount of ice it can produce in a 24 hour period without any interruption or stoppage? Assume that the ice maker works just like a refrigerator. The specific heat of water is 4184 J/(kg · °C), and the latent heat of fusion of ice is 33.4 x 104 J/kg. kg Additional Materials B Reading CS Scanned with CamScanner Tutorial

A heat engine uses a large insulated tank of ice water as its cold reservoir. In 100 cycles the engine takes in 8000 J of heat energy from the hot reservoir and the rejected heat melts 0.0180 kg of ice in the tank. During these 100 cycles, how much work is performed by the engine?
