SORU $24$

When the pump in the figure draws $220\frac{m^3}{h}$ of

water at $20C$ from the reservoir, the total friction

head loss is $5m.$ The flow discharges through a

nozzle to the atmosphere. Estimate the pump

power in $kW$ delivered to the water.

gravity, $g=9\mathrm{.}81\frac{m}{s^2}$

density, $=998k\frac{g}{m^3}$

$\frac{p_1}{g}+\frac{v_1^2}{2g}+z_1+h_p=\frac{p_2}{g}+\frac{v_2^2}{2g}+z_2+h_L$

Pump power, $P=gQ{h}_p$
