wrte the energy and entropy balances for the Heat Transfer Limited (HTL) Camot cycle. Assume the HTL Carnot cycle is intemally reversible and extemally irreversible. The HTL Carnot cycle operates between a heat source temperature, TH600K, and heat sink temperature, T 300K. Assume the overall heat transfer coefficient multiply by the heat exchanger area (UA) of the high and low temperature heat exchanger are equal, i.e, UA UA, = 10 kW/K Using the LaGrange Multipliers method to find the maximum...

4. The pressure-volume diagram below shows a special reversible cycle called the Carnot cycle A mole of an ideal gas starts off in state 1 in contact with a large thermal reservoir at temperature Th. The gas then undergoes an isothermal expansion from Vi to V2. Upon reaching state 2, the gas container is removed from contact with the thermal reservoir and covered with thermal insulation. Next the gas is allowed to expand adiabatically from V2to Vs. Because the expansion...

A "thermodynamic cycle” is a process that creates state changes in a gas in such a way that the final state is the same as the initial state. Such a process thus forms a closed path in the T-s diagram, and one "cycle” of the process corresponds to one complete progression around this closed path. The "net work” Wner produced by one cycle is the difference between the total work done by the gas and the total work done on...
