Problem 57HP

Consider a piston/cylinder setup with 0.5 kg of R-134a as saturated vapor at−10°C. It is now compressed to a pressure of 500 kPa in a polytropic process with n = 1.5. Find the final volume and temperature and determine the work done during the process.

Solution 57HP

Step 1 of 4

In this problem, we have to find the final volume, temperature and also determine the work done. The given data are

is the pressure

is the temperature and in kelvin it is

is the mass where

polytropic index.
