Document Summary

Consider now an incompressible liquid (i. e. , a fluid where the. A perfect gas in an automotive piston-cylinder arrangement has a volume of 50 cc, a pressure of 5,000 kpa, and a temperature of 2,800 k at the start of the expansion stroke. The compression ratio of the engine is 6:1. The working fluid is a perfect gas with cp = 1,250 j/kg-k and a specific heat ratio of 1. 3. The process is adiabatic and frictionless and only expansion work is done. Find the following: (a) the mass (kg) of gas in the piston. (b) the final volume (cc), pressure (kpa), and temperature (k) of the gas. (c) the work done (j). A fluid undergoes an adiabatic and frictionless process in which its pressure is raised from 100 to 200 kpa.
