ft-lbf/lb
ft-lbf/sec
✅ The correct answer is option C.
Cd for the orifice plate varies from
0.58 to 0.8
0.93 to 0.98
0.2 to 0.3
0.02 to 0.03
✅ The correct answer is option A.
Various efficiencies of a centrifugal pump are related as (where, ηm = mechanical efficiency ηv = volumetric efficiency. ηma = manometric efficiency ηo = overall efficiency)
ηma x ηm x ηv = ηo
ηm = ηv . ηma
ηma = ηm x ηv
ηv = ηm x ηma
✅ The correct answer is option B.
