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 1.1 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.

15. The partial pressures of a mixture of gases are 20 kPa (N2), 60 kPa (O2), and 80 kPa (CO2). If 20 kg of the mixture is inside a tank at 60°C and 300 kPa, find the volume of the tank.
4-A rigid tank is divided into two compartments by a partition. One compartment contains 3 kmol of N₂ at 600 kPa pressure and the other compartment contains 7 kmol of CO₂ at 200 kPa. Now the partition is removed, and the two gases form a homogeneous mixture at 300 kPa. The partial pressure of N₂ in the mixture is (a) 75 kPa (b) 90 kPa (c) 150 kPa (d) 175 kPa
Hydrogen is mixed with oxygen in an adiabatic mixing chamber at 100 kPa, 25 ∘C. The flow rate of hydrogen is 4 kmol/s and that of oxygen is 1 kmol/s. The mixture leaves the chamber at 100 kPa. Assume no chemical reaction and use the PG mixture model. Part A Determine the temperature at the exit (T2). Express your answer to three significant figures. Part B Determine the rate of entropy generation (S˙gen) in the device. Express your answer to four significant figures in kW/K.
2. An insulated tank that contains 1 kg of CH4 at 15°C and 300 kPa is connected to a 2 m³ uninsulated tank that contains C₂H6 at 50°C and 500 kPa. The valve connecting the two tanks is opened, and the two gases form a homogeneous mixture at 25°C. Assume To = 25°C. By analyzing the adiabatic gas mixing process calculate the: a) final pressure in the tank. b) heat transfer.
Q5) A rigid vessel of 1.5 m capacity, contain oxygen at 7 bar and 40 °C. the vessel is connected to another vessel of 3 m° capacity containing carbon monoxide at 1 bar and 15 °C. A connecting valve is opened and gases mixes adiabatically. Calculate the final temperature and pressure of the mixture.
The partial pressures of a four-component gaseous mixture (CO, CH4, N2, A) at 90 deg F are respectively: 7, 21, 14, 28 psia. For the mixture, find its pressure in kPa.
Steam at a pressure of 3.5 MPa is known to have a specific volume of 50x10 m³/kg. Find the enthalpy of the mixture in kJ/s if the mass flow rate of the steam is 7.667 kg/s.
5. By analyzing the mollier diagram for water vapor, what is the enthalpy (KJ/Kg) when P = 2100 kPa and T = 240 C?
