The water surface of the reservoir is at an elevation of 326 m. A penstock with a length of 6.4 km supplies water

from the reservoir to a power plant at an elevation of 18m above sea level. If the turbine inlet pressure is 2.4 MPa,

estimate the head losses in the penstock.

Solutions

Expert Solution

Dear student, this problem is purely related to calculation of head loss without considering friction losses in penstock. So this can be solved using Bernouli's principle.

Solution is provided followed by a short-cut procedure for solving smilar problems.

For a small scale hydraulic power system, the elevation difference between the reservoir water surface and the pond water surface downstream of the reservoir is 20.35. The velocity of the water exhausting into the pond is 7 m/s, and the discharge through the system is 4 m3/s. The head loss due to friction in the penstock (inlet pipe to turbine, under very high pressure) is negligible. Find the power produced by the turbine in kilowatts. Assume specific weight of water...

Water at 70°F flows by gravity from a large reservoir at a high elevation to a smaller one through a 55-ft-long, 2-in-diameter cast iron piping system that includes four standard flanged elbows, a well-rounded entrance, a sharp-edged exit, and a fully open gate valve. Taking the free surface of the lower reservoir as the reference level, determine the elevation z1 of the higher reservoir for a flow rate of 10 ft3/min. The density and dynamic viscosity of water at 70°F...
