Well pump head loss.

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. Example of total head calculation. In table 4 the head loss drops rapidly as the id increases. Write down the total friction loss in feet of head meaning the number of feet you lose from your pumping lift because of friction.

The vertical rise and friction loss. Your pump will need at least 30 ft. Static height is the maximum height reached by the pipe after the pump also known as the discharge head. Total dynamic head in an industrial pumping system is the total amount of pressure when water is flowing in a system.

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

Tdh static height static lift friction loss. This reduction in pipeline head loss allows for the selection of a smaller pump that requires less power. Plus the friction loss to get the required flow at the discharge point. It is comprised of two parts.

Static lift is the height the water will rise before arriving at the. The total head is the sum of the static head remember that the static head can be positive or negative and the friction head. 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. Look up these values on a pipe friction loss chart such as this one.

How to calculate total head of pump. The pump head hydraulic head or piezometric head is a specific measurement of liquid pressure above a specific point. Then select a pump based on flowrate and total head loss requirements. Total dynamic head of pumps calculation.

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. 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. Hydraulic head or piezometric head is a specific measurement of liquid pressure above a vertical datum. Head loss refers to the total pressure losses sustained by the fluid as it flows from the suction point to the discharge point.

Most pump applications involve moving fluid to a higher level.
