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 0.15. (a) What is the magnitude of the internal energy that the athlete...

1. Heat engines A heat engine is a device that does work by exchanging thermal energy with its environment. All heat engines operate in cycles during which a system, also known as the working substance, passes through a series of thermodynamic processes returning repeatedly to each state. A. Device 1, shown at right, represents a heat engine operating between 900 K reservoirs at 900 K and 400 K. (The system interacting with the reservoirs...

11) In an electric power plant (a heat engine) energy as heat is input at a temperature of Ty and exhaust heat is output at a temperature of Tc. This heat engine has an efficiency that is 55% (0.55 times) that of an ideal engine operating between these same temperatures. If the maximum waste heat that can be output at Tc is Qout Joules per second (Watts), what is the maximum Work (electrical output) that can be provided by the...
