NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. A piston-cylinder device contains a mixture of 0.4 kg of H2 and 1.2 kg of N2 at 100 kPa and 300 K. Heat is now transferred to the mixture at constant pressure until the volume is doubled. Assume constant specific heats at the average temperature. Problem 13.067.a Piston Determine the heat transfer. Use the table containing the ideal-gas specific heats of various common gases. The heat transfer is kJ.

Instructions: Show your entire solution. Indicate which table from the steam tables you utilized in your solution. 41.149 kg per second of water at 0.03398675 kbarg and internal energy of 15000 kW is heated at constant pressure to saturated vapor and further heated at constant volume process until the pressure is quadrupled. Determine the ratio of the heat added during the constant volume process to the heat added during the constant pressure process.

Part D and E SOLVE CAREFULLY PART D Using the P–v and T–s diagrams show that in the isobaric process the saturated vapor state can be reached for arbitrary initial steam quality x1 whereas in the isentropic process the saturated vapor state can be attained only for x1 above a certain threshold value. What is the phase description of water in the final state when the saturation line is reached from the initial state below the threshold value? PART E : Determine this threshold value of x1 for the isentropic process with the initial temperature T1 = 150°C.
