Well Pump Head Loss

In table 4 the head loss drops rapidly as the id increases.

Well pump head loss.

The vertical rise and friction loss. This reduction in pipeline head loss allows for the selection of a smaller pump that requires less power. Static height is the maximum height reached by the pipe after the pump also known as the discharge head. Tdh static height static lift friction loss.

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. It is the height to which a pump can raise the water fluid up. Write down the total friction loss in feet of head meaning the number of feet you lose from your pumping lift because of friction. Head loss refers to the total pressure losses sustained by the fluid as it flows from the suction point to the discharge point.

Look up these values on a pipe friction loss chart such as this one. Hydraulic head or piezometric head is a specific measurement of liquid pressure above a vertical datum. It is comprised of two parts. 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.

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. 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. Static lift is the height the water will rise before arriving at the.

Most pump applications involve moving fluid to a higher level. Short tutorial on how to calculate total dynamic head of industrical pumps. It is important to calculate this accurately in order to determine the correct sizing and scale of pumping equipment for your needs. Then select a pump based on flowrate and total head loss requirements.

This calculator allows you to figure out the head loss for pump selection. Example of total head 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. Your pump will need at least 30 ft.

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. The pump head hydraulic head or piezometric head is a specific measurement of liquid pressure above a specific point. Total dynamic head of pumps calculation. 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.

In fluid dynamics total dynamic head tdh is the total equivalent height that a fluid is to be pumped taking into account friction losses in the pipe.
