Question
![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)
