![]() For the industry, the pump head calculation formula is a very common technical data. Pump head is an important working energy parameter of the pump. Generally speaking, hw occurs at the entrance, bend, valve, outlet, etc. ![]() To check the relevant literature, v is the flow velocity in the tube. Hw=&*v^2/2g, & is called the local head loss coefficient. Hw is the head loss, including the Darcy formula or Xie Cai formula for calculating the head loss hf and the local head loss hw hf along the path. The pump head H=z+hw z is the height difference of the pumping height, that is, the water level from the inlet to the water surface at the exit. Other units: Pa (kPa), atm (1 engineering atmosphere) ![]() It is represented by the letter H and is usually expressed by the height m of the liquid column. (1kg) The work done by the liquid, that is, the increase in energy of the unit weight of liquid after passing through the pump. Pump head calculation formula, how to calculate pump head?
