Calculation of pump head
Thread Content
For process design, a pump that can be used both for mixing and for loading ethanol into the tank is required. The tank has a diameter of 4 meters and a height of 5 meters; how should this pump be designed? A beginner in design, not sure where to start; seeking advice
Calculate the head based on pipeline losses, height, etc
The loading flow rate should be determinable; once a loading flow rate is chosen, the inner diameter of the pipe can be calculated to select an appropriate pipeline. Then, the friction coefficient and pipeline fittings are used to calculate the head loss Hf. Head H = Hf (head loss) + z (height from the suction inlet to the discharge outlet). The pump model can be selected based on the head. After that, the installation location is calculated based on the cavitation head allowed by the pump
Thank you. I’ve learned that. May I ask what standards a beginner in process design needs to learn at the initial stage? No one taught me, so I was left to read on my own there with no idea what to do
There are few seniors from design institutes in the coal chemical industry sector; we are all involved in chemical production. Why don’t you post a request for help in the craftsmanship section?
Head H = Hf (head loss) + z (height from the suction inlet to the discharge outlet). The pump model can be selected based on the head requirement, and the installation location can then be determined using the pump’s allowable net positive suction head.
