Transcribed Image Text:Open Channel Flow - Uniform Flow
A penstock of 1 m diameter and 5 km
length is used to supply water from a
reservoir to an impulse turbine. A nozzle
of 15 cm diameter is fixed at the end of
the penstock. The elevation difference
between the turbine and water level in
the reservoir is 500 m. consider the head
loss due to friction as 5% of the velocity
head available at the jet. Assume
unit weight of water = 10 kN/m³ and
acceleration due to gravity (g) = 10 m/s².
If the overall efficiency is 80%, power
generated (expressed in kW and rounded
to nearest integer) is
