A mass of 4.0 kg of R-134a at p1=140 kpa and T1= 20 cis contained in a gas tight frictionless piston cylinder device. The r-134a is now compressed to final pressure of pa=240 kpa. During the compression process, the pressure and temperature are related by P=av ^-1.86 , where a=84.5756 kpa-m^6 a) Show through your calculations that v1= .65756 m^3 and V2=.4228m^3 b) determine T2 in C c) Consider the piston cylinder device as a closed system. compute the work done to the system in kj d) compute the heat transfer to the system in kj 3. A rigid tank is divided into two portions. Portion A has a volume of Va=.02703 m^3 and Portion B has a volume of Vb=0.008 m^3 Initially , Portion A contains 10kg of saturated liquid water at 22,000 kpa, and Portion B is evacuated. The partition is then removed, eventually, the entire rigid tank is occupied by saturated water vapor at 22,000 kpa. Determine the amount of heat transferred to the rigid tank ,in kj , for the unrestrained expansion process.
