As oxygen flows from a point A to a point B its temperature increases from 50°C to 73°C and its absolute pressure decreases from 300 kPa to 240 kPa. Determine the change per unit mass in internal energy between the two sections. Express your answer using three significant figures. Au = kJ/kg Determine the change per unit mass in enthalpy between the two sections. Express your answer using three significant figures. Ah = kJ/kg
