Two boilers are operating steadily on 91,000 kg of coal contained in a bunker. One boiler is producing 1,591 kg of steam per hour at 1.2 factor of evaporator and an efficiency of 65% and another boiler produced 1,364 kg of steam per hour at 1.15 factor of evaporation and an efficiency of 60%. How many hours will the coal in the bunker run the boilers if the heating value of coal is 7,590 kCal/kg? 230.8 O 118.2 94.54 O 184.6 O 147.7

Refrigerant R-134a to the compressor of a refrigeration machine It enters at 140 kPa pressure and -10 °C, and exits at 1 MPa pressure. Volumetric flow of the refrigerant entering the compressor It is 0.23 m³/minute. The refrigerant enters the throttling valve at a pressure of 0.95 MPa and at 30 °C, and exits the evaporator as saturated steam at -18 °C. Adiabatic efficiency of the compressor It is 78%. Show the cycle in the T-s diagram. And; a) Calculate the power required to run the compressor. b) Calculate the heat absorbed per unit time from the cooled medium. ( COPSM=? ) c) Calculate, between the evaporator and the compressor, how much the pressure of the refrigerant drops and how much the heat gain.
A steam plant. the pressure levels are 10 kPa and 6000 kPa, and the steam leaves the turbine as saturated vapor. The pump efficiency is 0.70 and the turbine 0.75. determine the thermal efficiency of the plant
In a household refrigerator, the condenser is vertically mounted at the outer backof the unit, the freezer (evaporator) on the topmost compartment, and thevegetable compartment at the very bottom. Explain why?
Refrigerant vapor rejects 70 kW of heat as it passes through an air-cooled condenser. The condenser has an air-side area of 210 m2 and, based on this area, has an overall heat transfer coefficient of 0.037 kW/m2∙°C. Cooling air flows at a rate of 7.59 kg/s. If condensation of the refrigerant occurs at 55°C, what is the inlet temperature (in °C) of the air? Take the specific heat of air to be 1.02 kJ/kg∙°C. Round your answer to 2 decimal places.
In 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.
