Expert Answer:

Potential energy = mgh

Efficiency = 40 %

Useful work done = 40 % of potential energy

40 over 100 space left parenthesis m g h right parenthesis space equals space 0.4 cross times m cross times 10 cross times 50 space
equals space 200 space m space

P o w e r space equals space w o r k space d o n e space p e r space s e c o n d space
space 1 space M W space equals space 200 space cross times space m a s s space o f space w a t e r space f l o w i n g space e a c h space s e c o n d space
1 space cross times 10 to the power of 6 space space equals space 200 space cross times space m a s s space o f space w a t e r space f l o w i n g space e a c h space s e c o n d space
m a s s space o f space w a t e r space f l o w i n g space e a c h space s e c o n d space equals space fraction numerator 1 space cross times 10 to the power of 6 over denominator 200 end fraction space equals space 5000 space k g space
