As nitrogen flows from a point A to a point B its temperature increases from 40°F to 58°F and its absolute pressure decreases from 30 psi to 25 psi. Part A Determine the change per unit mass in internal energy between the two sections. Express your answer using three significant figures. Au = ft - lb/slug Part B Determine the change per unit mass in enthalpy between the two sections. Express your answer using three significant figures. Ah = ft - lb/slug • Part C Determine the change per unit mass in entropy between the two sections. Express your answer using three significant figures. As = ft - lb/[slug · °R]
