0.75 lbm of oxygen is initially at 30 psi and 50oF. The oxygen expands in an isobaric process until its volume is 6.2 ft3. Assuming the oxygen behaves as an ideal gas with constant specific heats, determine the change in total internal energy and total enthalpy of the oxygen during the process.
Given: m = 0.75 lbm; P1 = P2 = 30 psi (isobaric process); T1 = 50oF = 510 R; V2 = 6.2 ft3 What will be an ideal response?
