A 0.5 m3 tank contains R134A at ambient temperature of 20 C. 10% of the tank volume is vapor and the balance is liquid. The tank safety valve opens at 1000 kPa. The room temperature gradually rises to 40 C and the tank is heated. The valve opens and the Freon is released until the valve closes (the pressure drops slightly below 1000 kPa. A - At what temperature of the Freon will the valve open? B - What will be the condition of the Freon when the valve closes? C-Determine the mass of Freon remaining in the tank. D- Determine the amount of heat transfer into the tank.

A car tire, which should normally be at 36 psia pressure, has 25 0,C 0.10 kg N2 gas at 32 psia pressure. Because the mechanic does not have N2 gas, air is pressed into the car's tire to reach 36 psia pressure. Calculate the mass of added air. (Note: change in temperature can be neglected during the process. Gases do not react with each other.)

Inlet enthalpy at the given pressure P1 = 800 kPa and temperature T1 = 35°C is; h1 = 271.24 kJ/kg im not finding this on the table could someone help with this
The temperature before and after the adiabatic process is 200 K and 127°C. The pressure before the process is 500000 N/cm? and adiabatic index is 2.4, then its pressure after the process is approximately 800000 N/cm?
Saturated liquid R-134a at 24 °C is fed to an adjustable throttling valve that controls the amount of throttling. Analyze the following scenarios:a. The flow is throttled until the exit pressure is 0.32 MPa. Find the exit temperature and quality.b. The flow is throttled to obtain an exit temperature of -12.0 °C. Find exit pressure and quality.c. The flow is throttled until the exit quality is 0.167. Find the exit temperature and pressure. (This will require you to iterate a bit, but you should be able to get a trend by plotting how the quality varies with the temperature for the 3 state points above.)

A 130 L rigid tank initially contains nitrogen at 400 kPa, 100 K. Thetank is connected to a line which contains nitrogen at 10,000 kPa, 260 K.The valve is opened and nitrogen flows into the tank until half of thetank’s volume is filled with liquid nitrogen, at which point the valve isclosed. During the filling process heat is transferred from the tank tokeep the temperature constant at 100 K. Neglect KE and PE terms.Calculate the final pressure and quality, and the heat transferred inthe process.
