 #### Calculation to Determine Internal Diameter of Pipe for a Pumping System

In order to determine internal diameter (ID) of pipe for a pumping system, there are 2 parameters that we need to know which are flow in the pipe (Q), and its velocity (V). The formula is as shown in the picture below. Q is the required flow for the system that we design, while V […]

#### Calculation To Determine Engine Power For Hydraulic Submersible Pump

Firstly, we need to understand the distribution of power to transfer some amount of water (Flow) to the specified height (Total Head). The distribution of power for the hydraulic submersible pump is as follow: In order to determine the Engine power, we need to calculate the Brake Power at Hydraulic Pump Shaft in Hydraulic System. […]
