Unit discharge(Q') = Q/H^2.
So Q'= 2500/(100^2).
Therefore,
Q' = 0.25(B).
So Q'= 2500/(100^2).
Therefore,
Q' = 0.25(B).

In some other case answer as 1.75, Its a right or wrong?

Unit discharge = Q/(H)^(1/2).
Q = 2500 Lit. = 2.5 m^3.
Unit discharge = 2.5/(100)^(1/2) = 0.25.
Q = 2500 Lit. = 2.5 m^3.
Unit discharge = 2.5/(100)^(1/2) = 0.25.

@Ram Kumar
1.75 was unit power, unit speed is 20 rpm, unit discharge is 0.25.
1.75 was unit power, unit speed is 20 rpm, unit discharge is 0.25.
