"A fluid at a pressure of 7 atm with a specific volume of 0.11 m3/kg is constrained in a cylinder behind a piston. It is allowed to expand under an isothermal process(T = 23 oC) to a pressure of 0.85 atm according to the ideal gas law.a) Calculate the work done by the fluid in the piston. b) Calculate the specific gas constant of the gas. c) calculate the molecular weight of the gas"

Answer:

Work done by the fluid in the piston=164.5kJ/kg

Specific gas constant= 0.263 kJ/kg K

Molecular weight of gas= 31.54 kmol
