What is the THERMAL efficiency of each process? A completely insulated mixing vessel is designed to deliver water at 60 ⁰Cand atmospheric pressure at a rate of 4 kg/s by mixing two streams of incoming water in an environment at 25 ⁰C. Saturated steam at atmospheric pressure is inserted on the hot side. Two options are being considered for the cold side: (a) chilled water from the plant at 3 ⁰C or (b) water from the tap at 20 ⁰C (both at atmospheric pressure).

The refrigerant experiences a heat loss through the casing to the surrounding at a rate of 3 kJ/kg. The power input to the compressor is 640 kW. Determine (a) the mass flow rate of the refrigerant and (b) the exit temperature. R-134a
Air at a rate of 50 m3/min enters an adiabatic compressor at a pressure of 100 kPa and a temperature of 24.3 C and exits at 500 kPa and 189.55 C. It then enters an insulated heat exchanger where it gets cooled by water. The air exits the heat exchanger at a temperature of 57.35 C. Water enters the heat exchanger at 20 C and exits at 50 C. Calculate the compressor power in kW, the mass for rate of the cooling water in kg/sec, and the rate of entropy generation for the compressor and the heat exchanger. Assume a mean heat capacity of water at ?? = 4.18 ??/???. You may also assume that there is no pressure drop in the heat exchanger)

A vapor at a flow rate of 3 kg/s enters a group of eight (8)nozzles at 1.5 MPa, 240 oC and a velocity of 480 m/s, and then expands to 0.07MPa.

1. Steam at a pressure of 2MPA and temperature 300°C is passed at a constant rate into a desuperheater unit. The desuperheater is accomplished by continuously spraying water at 95 °C onto incoming superheated steam. The amount of water injected is so regulated that both the water and superheated steam finally change into dry steam at 2 MPa. If the resulting mixture of dry saturated steam leaves the desuperheater at 2MPA and the rate of I kg/s, find the mass of superheated steam used per hour and the mass of water to be injected per hour. Fond also the diameter of the pipe through which the superheated steam flows to the superheater if the speed of the steam through the pipe is not to exceed 25m/s..
A heat exchanger is to heat water (cp = 4.18 kJ/kg·oC) from 25oC to 60oC at a rate of 0.2 kg/s. The heating is to be accomplished by geothermal water (cp = 4.31 kJ/kg·oC) available at 159oC at a mass flow rate of 0.3 kg/s. Find the exit temperature of geothermal water.

Heat is rejected from the condenser of a heat pump cycle by refrigerant-134a entering at 700 kPa and 50 ◦C at a rate of 105 kg/h and leaves as a saturated liquid.

Steam at 1.6 MPa and 250°C is being throttled by an adiabatic steam valve to reduce its pressure to 0.5 MPa before it is being delivered to a heat exchanger (shown in Figure 1). At valve outlet, the steam at18,000 kg/hour flow into an adiabatic heat exchanger as hot fluid. Cooling water from water tap is used to cool the steam by circulating the water through the tubes inside the heat exchanger. At heat exchanger outlet, the cooling water temperature increased by 20°C as it passing through the heat exchanger, and steam leaves the heat exchanger as saturated vapor at 200 kPa. Determine: (a) the temperature of the steam at heat exchanger inlet; and (b) the mass flow rate of the cooling water required.
