A power generation system with a turbine and a generator is located at a dam, where the water falls from 106.074 m height to the turbine. Assuming turbines having 100% efficiency, what should be the flow rate of water (in kg/s) to produce 7.486 MW of power? (Take gravitational acceleration as 9.81 m/s2.

3. A pump draws water at 15°C from a well through 10 m of 3 inch sch 40 steel pipe. The pump is 7 m above the water level in the well. The pump discharges the water -horizontally through 30 m of 3 inch sch 40 steel pipe to a sprinkler. There is one check valve (ball type), and three 90° standard elbow installed at various places in the system. The pressure into the sprinkler should be 500 kPa and...

A pumping system is designed to pump from a storage reservoir located at an elevation of 1015 feet. The pump elevation is 1005 feet. The pump discharge flowrate is 4500 gpm and the water temperature is 100˚F (1 atm). Between the storage tank and the pump is 30 feet of 14-in DIP pipe (f = 0.018) with one rounded entrance (kent = 0.05), and two 45 -degree bends (k45 = 0.30). What is the NPSH (in ft) for this system?...

A wind turbine is located 1000 m from the seashore and exposed to winds at 30 km/hr. The blades of the turbine are 20 m in length. In order to avoid lower wind velocity near the ground, the turbine tower is placed high enough so that the blades are at least 3 m above the boundary layer. What should be the height of the axis of the turbine? Use air properties at 10 C, and assume the boundary layer is...

Water is pumped from a well to a water tower (an above-ground reservoir) through a 330 ft long galvanized iron pipe (ε-0.0005 ft) with a 2-in diameter. The water surface in the well is 10 ft below the ground and the water surface in the tower is 60 ft above the ground. The water is to be delivered at a rate of at least 370 L/min. The sum of the minor loss coefficients is 2.1 a) Using the pump performance...
