1.A turbine located 225 m below the water surface at intake, carries a flow of 3.5 m^3/s. The head loss in the pipeline leading to it is 10 m. Find the power (kW) delivered by the turbine if its efficiency is 92%.
2.Head loss and sunshine striking a pipeline cause the temperature of the water flowing inside to rise by 2 degrees Celsius between two measuring points. Find the heat gain in J/N and cal/N.
3.Water at 60 degrees Fahreneit flows at 3 cfs through a 150-ft-long duct of 6 in X 9 in cross section. The pressure at the inlet end is 15 psig, and at the outlet, 20 ft higher than the inlet, it is 4 psig. Find the wall friction head loss, and the friction force on the duct. Neglect energy losses caused by bends.
