Paano ko kakalkulahin ang pump power?

P=ρgQH/η. ρ=density, g=9.81, Q=flow(m³/s), H=head(m), η=efficiency.

Ano ang tipikal na pump efficiency?

Small: 50-65%. Medium centrifugal: 70-80%. Large: 80-90%.

Hydraulic=useful fluid power. Shaft=hydraulic/efficiency. Motor≥shaft power.

P(bar)=ρgH/100000. Water: 10m≈1bar.

Net Positive Suction Head. Insufficient NPSHa causes cavitation.

Kalkulahin ang pump power mula sa flow rate, head, density, at efficiency. P=ρgQH/η.

P = ρgQH/ηkW & hp
