Explain why?arrow_forwardThe steam from a boiler enters a steam turbine and work is done by the steam turbine. After work done, the steam is condensed by condenser. The condensate (water) is again sent to the boiler to generate the steam. Choose the correct type of thermodynamic system involve in this operation. O a. Open system O b. Adiabatic system O C.

A refrigeration system using R-22 has a capacity of 320 kW of refrigeration. The evaporating temperature is -10°C and the condensing temperature is 40°C. Calculate the fraction of vapor in the mixture before the evaporator. Properties of R-22: At -10°C; hg = 401.60 kJ/kg, hf = 188.43 kJ/kg At 40°C; hf 249.69 kJ/kgarrow_forward
- Are internal combustion engines going away?arrow_forwardWhy is it important to clean the condenser coils of a household refrigerator a few times a year? Also, why is it important not to block airflow through the condenser coils?arrow_forwardIn a closed feedwater heater, steam warms the feedwater and the condensate leaves the heater through a trap or throttling value . What is the purpose of the trap or throttling value? It allows the liquid to flow to higher pressures with the same internal energy. It separates the liquid from the vapor. It allows the liquid to flow into a lower pressures without the loss of enthalpy. It allows the liquid to flow to higher pressures with the same enthalpy. It allows the liquid to flow into a lower pressures without the loss of internal energy.arrow_forward
