1.Select a pump to be used to supply water to a reservoir at a flow rate of 30 L/sec. The elevation head is 20 m and the distance between the supply and delivery is 100 m. A ball check valve is used with 15-cm diameter galvanized iron pipeline. Determine the working conditions. Assume a k-value of 70.
2.Calculate the stress at failure of a concrete test cylinder with a measured diameter of 152.4 mm and a recorded load of 371,426N. Units of ksi.
3.The following data is available for a hydropower plant : Available head = 130 m; Catchments area = efficiency = 220 sq. km; Annual average rainfall = 150 cm; efficiency = 91% percolation and evaporation , losses = 18 %. Determine power developed in MW taking load factor as unity
