Using the compressibility chart, determine the volume, in m3, occupied by 20 kg of hydrogen (H2) at 11.55 atm and -364 °F. 2.Determine the percent error in using the ideal gas model to determine the specific volume of water vapor at 4000 psi and 1000 °F. 3. 0.1 moles of an ideal gas contained in a piston-cylinder assembly undergoes the heat pump cycle shown below. The cycle operates counter-clockwise. Evaluate the coefficient of performance. Assume Cv for the gas is 3/2*R, where R is the ideal gas constant. Path 3->2 is isothermal and Path 4->3 is adiabatic. The pressure and volumes associated with states 1, 2, 3, and 4 are State 1: P = 0.39 Bar, V = 1.0 L State 2: P = 9.00 Bar, V = 1.0 L State 3: P = 2.00 Bar, V = 4.5 L State 4: P = 0.39 Bar, V = 12.0 L.
