A wind generator is installed. It is determined that the capacity factor of the installation is 29% over the course of a 90-day period. In that period, it produced 1566 MWh. What is the size of the installation (MW)?

Solve the ff. The discharge pressure of an air compressor is 5 times the suction pressure. If the volume flow at suction is 0.7m3/s and discharge volume flow of 0.2217m3/s,  what is the compressor power(hp) if  suction pressure is 100kpa. Ans. 191.72 A double acting air compressor has a cylinder dimension of 50cm x 60cm, 750rpm will have a volume displacement (m3/s) of:  Ans. 2.945 A pump has a specific speed of 45 and 600rpm when it delivers 0.01m3/s. Find the head developed by the pump in ft. Ans. 926.07

Given the sketch shown below, the diameter of the plunger Dp = 8 cm. The Ram diameter is Dr = 48 cm. The efficiency is 100%, the stroke of the plunger is 18 cm. The ram has to raise a load F2 = 2kN. Find: A) the force f1 exerted on the plunger. B) the number of strokes needed to raise the load given above by a distance of 10 cm. C) the volume of oil pumped if the load moves by 20 cm ( using plunger force in a ) D) what will be the new diameter of the ram piston if the new load force is 16 times the force exerted in the plunger the diameter of the plunger is kept to 8 cm.

n engineering team is to stop a water turbine for maintenance. During the shutdownprocess, the angular acceleration d of the turbine is given by:a=-0.02w, where a is rad's and the angular velocity w is in rad/s. a) Calculate the time for the angular velocity to decrease from 10000 rewmin to 1000rev/min.
