Solve problem no. 14-123 Refer problem 14-122 14–122 A 1.8-m³ tank contains saturated air at 20°C and 90 kPa. Determine (a) the mass of the dry air, (b) the spe- cific humidity, and (c) the enthalpy of the air per unit mass of the dry air. Answers: (a) 1.88 kg, (b) 0.0166 kg H,O/kg dry air, (c) 62.2 kJ/kg dry air Reconsider Prob. 14–122. Using appropriate software, determine the properties of the air at the initial state. Study the effect of heating the air at constant volume until the pressure is 110 kPa. Plot the required heat 14-123 transfer, in kJ, as a function of pressure.
