n a power plant operating with water and steam, the following measurements and observations were done at various stages along the system.  the temperature is190oC and the specific volume, v is 0.15636 m3/kg. Based on this observation, identify the following values: pressure, P (in kPa) = _____, and enthalpy, h (in kJ/kg) = _____

Saturated steam at P1=25 bar expands adiabatically through a throttling valve to P2=4 bar. If the quality of the steam at the valve inlet is x1=0.9 what is the quality x2 at the valve outlet Please respond ASAP

An oxygen gas R = 0.2598 KJ/kg°k and k = 1.395. If 4 kg of oxygen undergo a reversible non flow constant pressure process from initial volume =1.2 cubic meter and initial pressure = 690 kPa to a state where final temperature = 600°C. From the above statement: What is the initial temperature ? * 786.76°K 797.10 °K 876.50°K 796.77 °K Other: Determine the constant volume specific heat. * 0.6580 KJ/Kg-°K 0.6568 KJ/Kg-°K 0.5897 KJ/Kg- K 0.6577 KJ/Kg-°K

An air-conditioning system made up of a compressor and heat exchanger is shown in the figure below. This system is operating at steady-state with air flowing through the heat exchanger while the refrigerant first flows through a compressor before entering the heat exchanger. The refrigerant and air do not mix in the heat exchanger. Two control volumes are defined in the figure and both of these control volumes are to be used to answer the questions from this problem. Rotating Shaft 3 Compressor Refrigerant 12 I Control volume B wwwwwww wwwww Heat Exchanger 1 1 I 5 Air Control _' volume A The air enters the heat exchanger (inlet marked 1 in the figure) at a temperature of -13 °C, volumetric flow rate of 0.03 m³/min, and pressure of 101 kPa. Upon exiting the heat exchanger, the air is at a temperature of 42 °C (outlet marked 2 in the figure). The air can be modeled as an ideal gas with gas constant of 287 J/kg.K. The refrigerant enters the compressor (inlet marked 3 in the figure) at a…
