How do you calculate pump power from head?
Pump Power P(HP) = q(m3/hr) x ρ(kg/m3) x g(m2/s) x h(m) x p(Pa) / 2685600. Also above pump power is required to lift the liquid to head meters.
What is pump head flow rate?
It defines the rate at which a pump can push fluid through the system. When selecting pumps, the rated operating or discharge pressure of the pump must be equal to or more than the required pressure for the system at the desired flow rate. Head is the height above the suction inlet that a pump can lift a fluid.
How do you calculate the power of a pump?
Efficiency and Input Power of the Pump The work performed by the pump is equal to the weight of liquid pumped in Unit time multiplied by total Head in meters. However the pump capacity in M3/hr and liquid specific gravity are used rather than weight of liquid pumped for work done by the pump.
What is flow pumping power?
Pumping power is calculated as the volume of the fluid per unit time (flow capacity) times the density of the fluid times the gravitational constant times the pumping head (vertical distance to be pumped). Pumping energy is simply power multiplied across time. 100kW of power for one hour is 100kWh of energy.
How much water can a 2 HP pump move?
Number of submersible well pump stages determine pump lift capacity
| Table of Submersible Pump Stages vs HP vs Total Dynamic Head vs. GPM Flow Rate Capacity | ||
|---|---|---|
| Water Pump HP | Nr. of Pump Stages | GPM Flow Rate Capacity |
| 1 HP | 8 | 4 – 40 GPM (varies by TDH) |
| 1 1/2 HP | 11 | 4 – 40 GPM (varies by TDH) |
| 2 HP | 14 | 4 – 42 GPM (varies by TDH) |

What is difference between pressure and pressure head?
By definition, ‘Head’ is a measure of energy. The units of energy are feet (or meters). ‘Pressure’ is a force applied against a unit of area such as a pound of force applied to a square inch of area (psi).
What is differential head of pump?
Differential head Think of a pump as ‘adding’ head to your system. For example, imagine a pump that ‘adds’ 20m head. If the head at the pump inlet is 5m then the discharge head will be 25m. The amount of head that the pump ‘adds’ to the system is called the ‘differential head’.
What is pump head?
Head is the height at which a pump can raise water up, that’s it, it’s that simple. Connect a tube to the discharge of a pump and measure the water height, that the head of the pump.
Why does pump head decrease with flow rate?
Increasing flow rate introduces friction into the system as the liquid travels along the pipes from the suction tank to the pump and from the pump into the discharge pipe. This friction reduces the amount of total head that the pump can produce.
What is the pump head of water pump?
The pump head or discharge head of a water pump is a measure of the power of a pump. The greater the pump head, the greater the pressure that the pump can generate. This statistic is measured in meters (or feet) and is calculated by placing a tube on a pump’s discharge and measuring the maximum height to which it can pump water.
What is the relationship between pump head speed and power?
• The pump head is directly proportional to the square of the pump speed: double the speed/multiply the pressure by four. • The power required by the pump motor is directly proportional to the cube of the pump speed: double the speed/multiply the power by eight.
How does the head of a centrifugal pump change with velocity?
The head will also change as the volumetric flow rate through the pump is increased. When a centrifugal pump is operating at a constant angular velocity, an increase in the system head (back pressure) on the flowing stream causes a reduction in the volumetric flow rate that the centrifugal pump can maintain.
What is the shaft power of a pump?
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 The calculator below can used to calculate the hydraulic and shaft power of a pump:
