Water flows from one reservoir to another a height, 41 m below. A turbine (η=0.77) generates power from this flow. 1 m3/s passes through the turbine. If 12 m head loss occurs between the two reservoirs, determine the actual (i. e. useable) power generated by the turbine (in kW).

Complete Question

A diagram representing this question is shown on the first uploaded image

The value is

Explanation:

From the question we are told that

   The height is  

   The efficiency of the turbine is

   The flow rate is

    The head loss is  g =  2 m

Generally the head gain by the turbine is mathematically represented as      

=>    

=>    

Generally the actual power generated by the turbine is mathematically represented as

Here is the specific density of water with value
