Hi, can you only help with part a of the following?
As the refrigerant as shown in the figure, R134a fluid is used in a commercial refrigerator. The refrigerant leaves the evaporator at a temperature of -33.5°C (239.65 K) and a pressure of 60 kPa. It is then compressed to a pressure of 1.2 MPa and a temperature of 64°C (337.15 K). In the water-cooled condenser, the refrigerant is cooled to 41°C (314.15 K). Water enters the condenser at 18°C and leaves at 26°C. In this context; *Calculate the degree of dryness (quality) of the refrigerant at the evaporator inlet [%].

Steam CERE KJ -Valve Control volume boundary Turbine Initially evacuated tank In case of emergencies, a turbine is connected to an active steam pipe line using a valve. When the valve is opened, steam from the pipe line, which is initially at 550°C and 10 MPa, flows through the turbine into a 0.64 m³ tank, which is initially evacuated. The valve is closed when the pressure inside the tank is 1.6 MPa and the temperature in the tank is 300°C. If the entire process is completed adiabatically, what is the amount of work generated from the turbine?
Q14//A surface condenser receives exhaust steam at 0.14 bar from an engine developing 180 kW. The circulating water enters the condenser at 15°C and leaves at 40°C. The final temperature of the condenser steam is 50°C. If the engine consumes 9 kg of steam per kW per hour, determine the quality of the steam entering the condenser, if the weight of circulating water per hour is 31600 kg. (Answer: x=0.85) ****
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.
