What is pump capacity formula?

What is pump capacity formula?

The theoretical pump power can be calculated as. Ph(kW) = (1 m3/h) (1000 kg/m3) (9.81 m/s2) (10 m) / (3.6 106) = 0.027 kW.

What is m3 HR in pump?

The flow rate, that is, the amount of liquid delivered per unit time, is most commonly used in m3/h, which is the number of squares that are often said. For example, if you need to transport liquid 80-100 squares per day and the boot time is 10 hours, then the pump flow range is 8-10m3/h.

How do you calculate water pump capacity?

WHP = HQ / 3960

  1. WHP = HQ / 3960.
  2. Where H is the change in pressure measured in height of water in feet and Q is the water flow rate in gallons per minute.
  3. WHP = (112 x 460) / 3960 = 13.0.
  4. So the pump is providing 13.0 WHP when it lifts water 112 feet at a rate of 460 gallons per minute.

What is pump head capacity?

This applied force or energy is quantitatively expressed in the pump’s head-capacity (H-Q) curve. This curve graphically expresses how much flow (Q) can be generated due to the increased head (H) (pressure), which is added to the fluid by the pump.

How many m3/h is pumped a head of 10 m?

1 m3/h of water is pumped a head of 10 m. The theoretical pump power can be calculated as The shaft power – the power required transferred from the motor to the shaft of the pump – depends on the efficiency of the pump and can be calculated as

How do you calculate the pressure of a hydronic pump head?

So, for hydronic applications, we can say that: For closed systems: Pump head = the sum of all friction pressure drops Where: Friction pressure drop = piping pressure drop + terminal unit pressure drop + source unit pressure drop* + valve pressure drop + accessories pressure drop.

How do you calculate the power of a power pump?

Pump Power calculation Formula: Pump power P (kW) in kilowatts is equal to the product of the rate of flow q (m3/hr) in cubic meter per hour, fluid density ρ (kg/m3) in kilogram per cubic meter, gravity g in m 2 /s, pump differential h (m) head in meter and the differential pressure p (Pa) in Pascal or N/m 2 divided by 36,00,000.

How do you calculate the combined efficiency of a motor and pump?

Use the formula, Where HP equals horse power (read as 0.746 KW equals 1 HP), H equals total head in meters, ¶-equals combined efficiency of pump & motor (around 0.8), Q-equals flow rate in M cube/hour. How do we calculate the efficiency of a pump?
