Well Pump Head Loss

Write down the total friction loss in feet of head meaning the number of feet you lose from your pumping lift because of friction.

Well pump head loss.

Most pump applications involve moving fluid to a higher level. It is important to calculate this accurately in order to determine the correct sizing and scale of pumping equipment for your needs. The vertical rise and friction loss. Static height is the maximum height reached by the pipe after the pump also known as the discharge head.

In table 4 the head loss drops rapidly as the id increases. All you do is enter your specifications and click the update button to calulate total losses for the system. Total dynamic head in an industrial pumping system is the total amount of pressure when water is flowing in a system. Plus the friction loss to get the required flow at the discharge point.

Head loss refers to the total pressure losses sustained by the fluid as it flows from the suction point to the discharge point. The pump head hydraulic head or piezometric head is a specific measurement of liquid pressure above a specific point. Look up these values on a pipe friction loss chart such as this one. You can select the pump based on the pump manufacturer s catalogue information using the total head and flow required as well as suitability to the application.

Your pump will need at least 30 ft. Tdh static height static lift friction loss. The total head is the sum of the static head remember that the static head can be positive or negative and the friction head. Hydraulic head or piezometric head is a specific measurement of liquid pressure above a vertical datum.

It is comprised of two parts. Example of total head calculation. Short tutorial on how to calculate total dynamic head of industrical pumps. The amount of friction depends on the pipe s material internal diameter and length as well as the type of bends and fittings you use.

Total dynamic head of pumps calculation. Head loss is caused when the liquid loses momentum as it flows and depends upon fluid viscosity pipe diameter pipe length and accessories such as valves and elbows within the pipework. For example transporting water through a 3 5 inch pipe results in 16 2 feet of head loss while a 6 inch pipe has a head loss of only 1 1 feet. How to calculate total head of pump.

This calculator allows you to figure out the head loss for pump selection. This reduction in pipeline head loss allows for the selection of a smaller pump that requires less power. If you have to pump a liquid up 30 feet and your pump doesn t have at least 30 feet of head then there is no chance it will work. It is usually measured as a liquid surface elevation expressed in units of length at the entrance or bottom of a piezometer in an aquifer it can be calculated from the depth to water in a piezometric well a specialized water well and given information of the piezometer s elevation.

It is the height to which a pump can raise the water fluid up.
