Professor Modyn owns a device called a pneumatic accumulator. This device maintains constant pressure of 194.00 psia as air enters by using a piston. Initially the device is filled with air at 74.240 °F and the volume is 0.217 fr (State 1). Air at 196.80 °F and 194.00 psia is fed into the accumulator until the volume triples and the temperature increases to 186.80 °F (State 2). Assume air is an ideal gas with a Cp = 3.5R and MW = 29. No air leaves the system. Find the amount of air added. 0.0116 air: Ibmol Incorrect Find the work interaction term. 1010.757 work interaction term: ft-lbf Incorrect Find the heat interaction term. 1197.91 heat interaction term: ft-lbf Incorrect
