- A heat engine operates between a reservoir at 28°C and one at 323°C. What is the maximum efficiency possible for this engine?Heat engines take input energy in the form of heat, use some of that energy to do work, and exhaust the remainder. Similarly, a person can be viewed as a heat engine that takes an input of internal energy, uses some of it to do work, and gives off the rest as heat. Suppose a trained athlete can function as a heat engine with an efficiency of 0.16. (a) What is the magnitude of the internal energy that the athlete uses in order to do 1.7x104 J of work? (b) Determine the magnitude of the heat the athlete gives off.Consider an engine with efficiency of 25%. How much must the temperature of the hot reservoir increase, so that the efficiency increases to 50%. The temperature of the cold reservoir remains at 5oC
- Suppose a heat engine design makes a square on a PV diagram, using a monatomic gas. The high pressure is 3P and low pressure is P. The high volume is 3V and low volume is V.
