Question

1. A hydro facility operates with an elevation difference of 50 m and a flow rate of 500 m3/s. If the rotational speed is 90 RPM, find the most suitable type of turbine and estimate the power output of the arrangement

Answer 1

Answer:

a) Pelton Turbine

b) $P=2.42*10^{5}KW$

Explanation:

From the question we are told that:

Height $h=50$

Flow Rate $R= 500 m^3/s$

Rotational speed $\omega=\90 RPM$

Let

Density of water

$\rho=1000$

Generally the equation for momentum is mathematically given by

$P=\rho gRh$

$P=1000*9.81*500*50$

$P=2.42*10^{5}KW$
