How much mass is compressed during each compression stroke

Reference no: EM13621053

A piston cylinder compressor is available for evaluation. The device has an initial volume at the beginning of compression stroke of 0.1m3. It compresses air (R=287J/kg-K, Cv=717.5J/kg-K), from an initial pressure of 101.325kPa, and 300K to a final pressure of 2x10^6Pa. The compression process can be analyzed as a closed system. The device provides compression with polytropic process Pv^1.2=constant.

a) How much mass is compressed during each compression stroke for these devices.

b) Find the final Temperature and volume of air before discharge.

c) What is the work input/output per unit mass of air, during the compression for [J].

d) What is the change in internal energy of the compressed air.

e) What is the loss/gain of heat during the compression? (apply 1st law, after evaluating U2-U1) [J/kg].
