The performance data for a centrifugal water pump are shown in Table P1428 for water at 20C

Question:

The performance data for a centrifugal water pump are shown in Table P14–28 for water at 20°C (Lpm = liters per minute).

(a) For each row of data, calculate the pump efficiency (percent). Show all units and unit conversions for full credit.

(b) Estimate the volume flow rate (Lpm) and net head (m) at the BEP of the pump.

TABLE P14-28 V, Lpm 0.0 6.0 12.0 18.0 24.0 30.0 36.0 H, m 47.5 46.2 42.5 36.2 26.2 15.0 0.0 bhp, W 133 142
