1. Water in the rural areas is often extracted from underground water source whose free surface is 60 m below ground level. The water is to be raised 5 m above the ground by a pump. The diameter of the pipe is 10 cm at the inlet and 15 cm at the exit. Neglecting any heat interaction with the surroundings and fictional heating effects. What is the necessary power input to the pump in kW for a steady flow of water at the rate of 15 li/s? Assume pump efficiency of 74%.
A cycle heat engine does 50 kJ of work per cycle If the efficiency of the heat engine is 75% The heat rejected per cycle is....

Would it be possible to use a normal domestic refrigerator as a heat source for a small hot tub or whirlpool? If so, what would you estimate to be the maximum heating rate and temperature that a 300 gal whirlpool could reach using a refrigerator that is sized to use a 1 hp electric compressor designed with an evaporator temperature of 10 ° F and condensing temperature of 125 ° F?

- .The thermal efficiency of a heat engine is 30%, the heat rejected from the engine is 30kJ, evaluate the heat input to the engine.arrow_forward5.49 Air in a piston/cylinder goes through a Carnot cycle with the P-v diagram shown in Fig. 5.21. The high and low temperatures are 600 K and 300 K, respectively. The heat added at the high temperature is 250 kJ/kg, and the lowest pressure in the cycle is 75 kPa. Find the specific volume and pressure after heat rejection and the net work per unit mass.arrow_forwardExample 2.3 In a steam power plant, the measured rate of steam supply was 7.1 kg/s when the net rate of work output (Actual We) was 5000 kW. The feed water was supplied to the boiler net at a temperature of 40 °C, and the superheated steam leaving the boiler was at 1.4 MPa and 300 °C. Calculate the thermal efficiency of the cycle, the corresponding net positive heat rate, the rational efficiency, and the turbine irreversibility.arrow_forward
