Centrifugal pump selection
Thread Content
Currently, it is necessary to transport styrene in vehicles; the pipeline has a diameter of DN50, and the maximum flow rate is 3.5 m/s. How should the head of this pump be calculated?
3.5 m/s, DN50 pipe, flow rate of around 25 cubic meters, friction loss along the pipeline is about 30 m/100 m
The design institute tells you that without knowing the flow rate and head, it is impossible to select a pump based on the flow velocity alone. Furthermore, for the proper operation of the pump, it is recommended that the flow velocity at the pump inlet be less than 3 m/s.
:The head can be easily calculated using Bernoulli’s equation. Knowing the flow velocity and pipe diameter, the flow rate can be determined using the formula flow rate = flow velocity * cross-sectional area. It is advisable to refer to the recommended economic flow velocities for different pipe diameters in China when determining the flow velocities at the inlet and outlet
Hello, sea friend! Once the diameter of the pipeline is known, the length and height difference of the pipeline are also required.
