In a constant pressure, nonflow process, 6Btus of heat are added to a gas while the volumes change from 1.6ft^3 to 2.0ft^3. If the temperature decreases by 10*F and the system contains 2 lbm of gas, find the pressure in the system. (Cv=.2Btu/lbm*F) 1Btu=778 ft-lbm© BrainMass Inc. brainmass.com October 9, 2019, 4:27 pm ad1c9bdddf

By adding a heat quantity of 6 BTUs to a non-flowing gas at constant pressure, its volume increases from 1.6 cubic feets to 2 cubic feets and the temperature decreases by 10 degrees Fahrenheit. If mass of gas is 2 lbm and Cv = 0.2 BTU/lb.deg.F, find the pressure. (1 BTU = 778 ft.lb)
We will apply the first principle of ...
The solution provides detailed explanations and step-by-step calculations for finding the pressure in a constant pressure system.
