This tool calculates the hydraulic power of a pump, shaft and motor power with efficiencies and recommends the appropriate standard motor power . If the runtime and electricity price are entered, the annual energy consumption and cost are also visible. It can be used for boiler feed pump, circulation pump and process pumps.
Formula
ρ: fluid density (kg/m³), g = 9.80665 m/s², Q: flow rate (m³/s), H: head (m). If the pressure difference is entered, H = Δp / (ρ·g).
Example
The hydraulic power of a pump delivering 50 m³/h of water at a head of 40 m is 5.45 kW, and the shaft power is 7.78 kW with 70% pump efficiency. An 11 kW standard motor with a 10% safety margin is recommended. The operating cost is approximately 203,000 ₺/year with 6,000 hours and 4 ₺/kWh of electricity per year.
You can find the pipe losses included in the head with the water pipe pressure loss tool. You can consult Çiftel Kazan engineers for your boiler room and plumbing project.
