A 0.2-m³ rigid tank initially contains saturated refrigerant- 134a at 1.0 MPa and 100 percent quality. The tank is connected by a valve to a supply line that carries refrigerant-134a at 1.6 MPa and 40°C. The valve is now opened, allowing the refrigerant to enter the tank, and it is closed when the tank contains only saturated liquid at 1.3 MPa. The refrigerant exchanges heat with its surroundings at 50°C and 100 kPa during this process. Determine (a) the amount of heat transfer and (b) the exergy destruction associated with this process.
Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Steam flows steadily through an adiabatic turbine. The inlet conditions of the steam are 4 MPa, 500°C, and 80 m/s and the exit conditions are 30 kPa, 92 percent quality, and 50 m/s. The mass flow rate of the steam is 13 kg/s. The properties of the steam are = 0.086442 m³/kg, h=3446 kJ/kg, and 2 = 2437.7 kJ/kg. P₁-4 MPa T₁ - 500°'℃ V₁-80 m's P₂ - 30 kPa 32-0.92 Vyu 30 m/s Determine the change in kinetic energy. (You must provide an answer before moving on to the next part.) The change in kinetic energy is kJ/kg.
A steady-flow compressor has R-134a entering at 120 kPa as a saturated vapor and exits at 800 kPa and 50°C, requiring 55 kJ/kg of work. Assume that the boundary of the compressor is at 30°C. What is the specific enthalpy of the R-134a at the inlet, in kJ/kg? What is the specific enthalpy of the R-134a at the outlet, in kJ/kg? How much heat transfer, in kJ/kg, exits the system?
Devices can be combined to perform a variety of tasks. An adiabatic compressor, with air as the working fluid, is to be powered by an adiabatic steam turbine, which is also driving a generator. Steam enters the turbine at 12.5 MPa and 500 ∘C at a steady rate of 27.30 kg/s and exits at 10 kPa and a quality of 0.8710. Air enters the compressor at 98 kPa and 295.0 K K at a steady rate of 12.600 kg/s and exits at 1 MPa and 635.0 K. For air, MW=29.0 g/mol, Cp=3.5R. Note: The IUPAC sign convention for work is used.
