Thermodynamics Problems 18-20 are based on the following description An Insulated rigid tank is divided into two equal parts by a partition. Initially, one part contains 10 kg of an ideal gas with molar mass M-16 kg/kmol, a pressure of 330 kPa, and a temperature of 50 oC. The other part is evacuated. The partition is now removed and the gas fills the entire tank. (R.- 8.31447 kJ/kmol.K) The expansion work in kJ is closer to: O 1678 O 725...

1.Water vapor contained in a piston–cylinder assembly undergoes an isothermal expansion at 277°C from a pressure of 5.1 bar to a pressure of 2.7 bar. Evaluate the work, in kJ/kg. 2.Nitrogen (N2) contained in a piston–cylinder arrangement, initially at 9.3 bar and 437 K, undergoes an expansion to a final temperature of 300 K, during which the pressure–volume relationship is pV1.1 = constant. Assuming the ideal gas model for the N2, determine the heat transfer in kJ/kg. 3.Argon contained in...
1. A rigid (constant volume) tank sealed by a valve initially contains 100 kg of air at a pressure of 100 kPa and 300 K. At time t = 0, the valve for the air tank is opened in a controlled manner and air leaks out isothermally (constant temperature) of the tank at a constant mass flow rate of 1 kg/s. The valve is closed after 75 seconds. Answer the following questions: Assuming air is an ideal gas, what is...
1.Argon contained in a closed, rigid tank, initially at 62.3°C, 3.9 bar, and a volume of 4.2 m3, is heated to a final pressure of 9.4 bar. Assuming the ideal gas model with k = 1.6 for the argon, determine the heat transfer, in kJ. 2.Water vapor contained in a piston–cylinder assembly undergoes an isothermal expansion at 223°C from a pressure of 5.4 bar to a pressure of 1.9 bar. Evaluate the work, in kJ/kg. 3.A mass of 4 kilograms...
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. _________________________________________________...
T(N)=352 please I need the answer urgent Question 1 The following gas phase reaction produces ethanol (C2H5OH) by catalytic hydrogenation of acetaldehyde (CH3CHO). The reaction reaches equilibrium at a temperature of T= T(N) and a pressure of 3 bar: CH,CHO(g) + H, (g) C,H,OH (8) The reactive system initially contains 1.5 moles of Hydrogen (Ha) for each mole of acetaldehyde (CH3CHO). The mixture is assumed to be an ideal gas. T(N) is the temperature corresponding to the student number as...
