Marks: +1, -0

Two pumps can operate independently at heads

H_1 , H_2

and discharges

Q_1 , Q_2

, respectively. If the pumps are connected in parallel, then what are the resulting discharge (Q) and head (H)?

Solution:

pump are parallel

Q = Q_1 + Q_2 + ........

H_1 = H_2 = H

when pump are in series

Q_1 = Q_2 = Q

H = H_1 + H_2 + .....
