Well Pump Head Loss

Most pump applications involve moving fluid to a higher level.

Well pump head loss.

It is the height to which a pump can raise the water fluid up. This calculator allows you to figure out the head loss for pump selection. It is important to calculate this accurately in order to determine the correct sizing and scale of pumping equipment for your needs. Head loss refers to the total pressure losses sustained by the fluid as it flows from the suction point to the discharge point.

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. Look up these values on a pipe friction loss chart such as this one. The vertical rise and friction loss. 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.

Plus the friction loss to get the required flow at the discharge point. Write down the total friction loss in feet of head meaning the number of feet you lose from your pumping lift because of friction. It is comprised of two parts. Static height is the maximum height reached by the pipe after the pump also known as the discharge head.

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. 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 amount of friction depends on the pipe s material internal diameter and length as well as the type of bends and fittings you use. Short tutorial on how to calculate total dynamic head of industrical pumps.

Total dynamic head of pumps calculation. Your pump will need at least 30 ft. 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. How to calculate total head of pump.

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. The total head is the sum of the static head remember that the static head can be positive or negative and the friction head. This reduction in pipeline head loss allows for the selection of a smaller pump that requires less power. Tdh static height static lift friction loss.

In table 4 the head loss drops rapidly as the id increases. Example of total head calculation. All you do is enter your specifications and click the update button to calulate total losses for the system. The pump head hydraulic head or piezometric head is a specific measurement of liquid pressure above a specific point.

Total dynamic head in an industrial pumping system is the total amount of pressure when water is flowing in a system.
