An engine uses a cycle with three parts: (1) An isotherm at 560 C going from a volume of 11 times 4.9 liters to 4.9 liters, (2) An isobar going from the high pressure side of the isotherm, (3) An isometric side going down from the high volume end of the isobar to the low pressure end of the isotherm. Find the % efficiency for 23 moles of gas, C sub v = 5, R = 2 cal/mole degree K with diagram

A cycle consists of an isotherm (T=624 K) going from a volume of 2.87 liters to a volume 7.54 times as large. An isometric side then decreases the pressure. Finally an adiabatic side returns the gas to the initial conditions. Find the percent efficiency. C sub v = 5 , R = 2 cal/mole degree K. answer: 31.4 diagram with explanation

This is a problem involving an engine with a three thermodynamic process cycle. We have an monatomic ideal gas in a cylinder that can expand and contract. The cylinder can be connected to a hot thermal reservoir at temperature, TH, and also can be connected to a cold reservoir at temperature, TC. We start out at temperture, TH, with Pressure P1 and volume V1. a)Keeping the cylinder connected to the hot reservoir we expand isothermaly to a new volume V2....
