Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part A 1.5-m3 rigid tank contains hydrogen at 250 kPa and 550 K. The gas is now cooled until its temperature drops to 350 K. The gas constant of hydrogen is R = 4.124 kPa-m3/kg-K (Table A-1). The constant-volume specific heat of hydrogen at the average temperature of 450 K is Cv, avg= 10.377 kJ/kg-K. Determine the final pressure...

Propane is compressed from an initial state with a pressure of 100 lbf/in2 and a quality of 0.40 to a final saturated liquid state with a temperature is 50°F. Is it possible for this process to occur adiabatically? Justify your answer. Air is contained in a rigid, well-insulated container of volume 3 m3. The air undergoes a process from an initial state with a pressure of 200 kPa and temperature of 300 K. During the process, the air receives 720...

CAN YALL PLEASE HELP ME I HAVE 4 HOURS TO DO THESE!! THANK YOU!! Question 1 A mass of 4 kilograms of air in a piston-cylinder assembly undergoes two processes in series from an initial state where p1 = 0.3 MPa, T1 = 211°C: Process 1–2: Constant-temperature expansion until the volume is twice the initial volume. Process 2–3: Constant-volume heating until the pressure is again 0.3 MPa. Assuming ideal gas behavior, determine the temperature at state 3, in kelvin. _________________________________________________...

QUESTION 10 A multi-stage high -pressure steam turbine is supplied with steam at a stagnation pressure of 7 MPa and a stagnation temperature of 500°C. The corresponding specific enthalpy is 3410kJ.kg. The steam exhaust from the turbine at a stagnation pressure of 0.7 MPa abs., the steam having been in a super-heated condition throughout the expansion. It can be assumed that the steam behaves like a perfect gas over the range of the expansion and that v...

6. To combat global warming, a conceptual thermodynamic cycle design is considered which uses CO, as working fluid. Consider 0.5 kg of CO2 is utilized in a piston-cylinder assembly for this cycle in which piston is massless and friction can be neglected. The cycle consists of three processes as follows. Process 1-92: CO, initially at 27°C and 100 kPa, is compressed isothermally to a pressure of 200 kPa. Process 2-3:...

Question Number 1 (25 Marks) A mass of 0.5 kg of ammonia is contained in a piston-cylinder assembly, initially at T1 = -20°C and U1 = 391.11 kJ/kg. The ammonia is slowly heated to state 2, where T2 = 20°C and P2 = 0.6 MPa, and the pressure varies linearly with specific volume during this process. From state 2, the system isºcompressed at constant pressure until the ammonia becomes a fully saturated vapor. Assume that there are no significant change...
