An oil pump is drawing 35kW of electric power while pumping oil with p = 860 kg/m³ at a rate of 0.1 m³/s. The inlet and outlet diameters of the pipe are 8cm and 12cm, respectively. If the pressure rise of oil in the pump is measured to be 400 kPa and the motor efficiency is 90 percent, determine the mechanical efficiency of the pump. Take the kinetic energy correction factor to be 1.05.

Water enters a pump at 350 kPa at a rate of 1 kg/s. The water leaving the pump enters a turbine in which the pressure is reduced and electricity is produced. The shaft power input to the pump is 1 KW snd the shaft power output the turbine is 1 kW. Both the pump and turbine are 90% efficient. If the elevation and velocity of the water remain constant through out the flow and irreversible headloss is 1 m, the pressure of water in kPa at the turbine exit is (WITH FREE BODY DIAGRAM) CHOICES: A.126 B.127 C.129 D.131
An electric motor with an efficiency of 80% drives the pulley system shown to lift a 400 kg crate. After the motor is turned on the system reaches a constant lifting speed vo and the motor is drawing 15 kW.

The blades of a wind turbine turn a large shaft at a relatively slow speed. The rotational speed is increased by a gearbox that has an efficiency of 0.93. In turn, the gearbox output shaft drives an electric generator with an efficiency of 0.95. The cylindrical nacelle, which houses the gearbox, generator, and associated equipment, is of length L = 6 m and diameter D = 3 m. If the turbine produces P = 2.5 MW of electrical power, and the air and surroundings temperatures are T = 25 oC and Tsur = 20 oC, respectively, determine the minimum possible operating temperature inside the nacelle. The emissivity of the nacelle is 0.83, and the convective heat transfer coefficient is h = 35 W/m2 .K. The surface of the nacelle that is adjacent to the blade hub can be considered to be adiabatic, and solar irradiation may be neglected. Use Fin or N number of fins to reduce the Ts of the nacelle less than 143 oC
Consider an under ground 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.
