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

So

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
