3. In the following take Cv = 5 and Cp = 7 Btu/lbmole-°F for nitrogen gas. (a) Three Ibmoles of nitrogen gas at 70 °F, contained in a rigid vessel, is heated to 3250 °F. How much heat is required if the vessel has negligible heat capacity? If the vessel weighs 200 lbm and has a heat capacity of 0.12 Btu/lbm-°F, how much heat is required? (b) Four Ibmoles of nitrogen at 400 °F is contained in a piston/cylinder arrangement. How much heat must be extracted from this system, which is kept at constant pressure, to cool it to 150 °F if the heat capacity of the piston and cylinder is neglected?

Transcribed Image Text:3. In the following take Cv = 5 and CP = 7 Btu/lbmole-°F for nitrogen gas.
(a) Three Ibmoles of nitrogen gas at 70 °F, contained in a rigid vessel, is
heated to 3250 °F. How much heat is required if the vessel has negligible
heat capacity? If the vessel weighs 200 lbm and has a heat capacity of
0.12 Btu/lbm-°F, how much heat is required? (b) Four Ibmoles of nitrogen at
400 °F is contained in a piston/cylinder arrangement. How much heat must
be extracted from this system, which is kept at constant pressure, to cool
it to 150 °F if the heat capacity of the piston and cylinder is neglected?
