Q2: Water from a reservoir passes over a dam and through a turbine and discharges from...
35. (a) A reservoir A discharges water to a lower reservoir B through a 3600 m long pipe of diameter 600 mm. The flow is due to gravity and the difference in surface water levels in A and B is 13 m. Reservoir A is now required to supply water also to a third reservoir C, the water surface of which is 15 m below that of A. The discharge to C is to be made from a 1200 m...
The fresh water behind a reservoir dam is 15.0 m deep. A horizontal pipe 2.50 cm in diameter passes through the dam 7.5 m below the water surface, as shown in the figure. A plug secures the pipe opening. Find the magnitude of the frictional force between plug and pipe wall. The plug is removed. What volume of water flows out of the pipe in 2.0 hours?
Problem 4: Water is being discharged from a reservoir through a turbine, as shown in figure below. The head loss for the 300-mm pipeline is 0.05 m/m (0.05 m per meter of pipe), and it is 0.0017 m/m for the 600-mm pipe a) Determine the elevation of the water surface in the reservoir that should be required in order for the turbine to generate 56 kW of power b) What would be the water elevation required in the reservoir if...

Q4. A pump draws water from a large reservoir and delivers it to another reservoir whose water surface is 10 m higher than the pump centreline and that the pump is 1.5 meter above the suction reservoir. The total suction and deliver pipe used is 21.1 m in length, 9 cm in diameter and has a Darcy friction factor f0.0339. The pump operates at 750 rpm and its characteristic performances are given in table below: Q (m3 s H (m)15...
In a hydroelectric power station, the turbine is driven by water flowing from a reservoir at the rate of 551 m s. The water is pumped through a pipe 2.06 km long of 2.53 m intemal diameter with a friction factor of 0.004. The water is assumed to have a kinematic viscosity of 13x10 mʻls. The elevation of the upper reservoir above sea level is 400 m and that of the lower reservoir is 40 m. Determine the following Mean...
Exercise 2: A pipe brings water, with a mass density Pwater, from a dam to the turbine of a hydroelectric plant. The cylindrical pipe, of constant diameter D30.0 cm and length L200 m, ends horizontally, its axis being located at H- 120 m below the free surface of the water in the dam of very big capacity. The departure of the pipe is at Ho- 20 m below the level of the free surface of the dam considered constant. The...
water 248 m 945 ml 2 Water Pipe GENERATOR TURBINE 1) A dam in somewhere with a height of 248 m, is one of the tallest dam in the world. Water flows with a volumetric flow rate of 65 m'ls to a turbine, where electric power is generated. The total irreversible head los in the piping system from point 1 to point 2 (excluding the turbine unit) is determined to be 95 m. The pressure difference due to elevation cannot...

A golf course sprinkler system discharges water from a horizontal pipe at the rate of 7100 cm3/s . At one point in the pipe, where the radius is 4.20 cm , the water's absolute pressure is 2.45×105 Pa . At a second point in the pipe, the water passes through a constriction where the radius is 1.75 cm . What is the water's absolute pressure as it flows through this constriction? (in Pa)
