ANSWER= [A] 0.005 m3/s
Detailed Solution for Civil Engineering Exam
Given data
Double acting reciprocating pump
A = 0.1m2
L = 0.30m
Q = 2.4 m2/min. N = 45rpm
H = 10 m
Slip of pump
Slip = Qth – Qout
Qth = 2ALN/60
Qth = ( 2 * 0.1 * 0.30 * 45 ) /60
Qth = 0.045 m3/s = 2.7 m3/min
Slip = Qth – Qout
Slip = 2.7 – 2.4 = 0.3 m3/min
0.005 m3/sec
