and is expanded isentropically to 0.04 bar in low pressure turbine, while the saturated liquid leaving
the separator is returned via a feed pump to the boiler. The condensate leaving the condenser at 0.04

A flash chamber has R-134A entering with a quality of 0.25 at a pressure of 5 bar. The saturated liquid from the flash chamber goes through a throttling value, an evaporator, and a compressor where it is compressed to 5 bar and 40°C. The saturated vapor from the flash chamber recombines with the remaining refrigerant in an open heat exchanger at a pressure of 5 bar. What are the enthalpy and temperature of the refrigerant exiting the heat exchanger?
Thermodynamics Question: Refrigerant – 134a is to be cooled by water in a condenser. The refrigerant enters the insulated condenser with a mass flow rate of 6 kg/min at 1 MPa, 70 oC and leaves at 35 oC. The cooling water (compressed liquid) enters at 300 kPa and 15 oC and leaves at 25 oC. Neglecting any pressure drops, kinetic and potential energy changes in the pipes, determine (a) the mass flow rate of the cooling water required and (b) the heat transfer rate from the refrigerant to water.

A car wash service uses 150 litre of pressurized (3 bar) warm water (45oC) to wash each car. It takes 10 min to wash each car. The service has 10 washing lanes, and it is open from (14:00 to 21:00) every day and 360 day per year. Each day 400 cars are washed. Fresh water at 1 bar pressure and 15oC is pressurized in a pump and then heated to desired temperature. Assume pump operates adiabatically and its efficiency is 85%, which is defined as the ideal power input divided by the actual power input. The ideal power input is the product of the volumetric flow rate times the pressure drop across the pump. All the other equipment of the car wash uses 5 kW of power during operation. Current (first alternative) is to buy electricity from the utility and use a natural gas fired boiler to heat the water. Assume natural gas furnace used in heating has 90% overall efficiency defined as heating provided water to heating released from fuel. The heating value of the natural gas (CH4) is 55.5 MJ/kg,…
