Piping design pressure
Thread Content
The operating pressure of the liquid preparation tank is 0.3 Mpa. The infusion pump has a flow rate of 3 m3/h and a head of 15 m, with an operating pressure of 0.15 Mpa. What should be the design pressure of the pipes? What diameter of pipe is suitable?
This question is a bit unclear. . . What liquid is this paired with? Does the pump pump into the mixing tank or out of it? . . Also, why is the operating pressure of your pump 0.15 MPa...? ? ? Is the head 15m, and the pressure is 0.15MPa? ? Where is there such a rule? . The design pressure of the pipeline here should be determined by multiplying the maximum shut-off pressure at the pump outlet by a certain coefficient. . . As for the pump outlet shut-off pressure, you’ll have to calculate it yourself! The pipe diameter is calculated based on the flow velocity and flow rate corresponding to the properties of the medium. . .
