A fire extinguishing hose is required to spray water at a rate of V=400 L per minute, with a horizontal spray distance of m=30 meters. How to choose a centrifugal pump? In other words, how should the parameters of a centrifugal pump be selected? What power level is required, and what should the operating pressure be? I’m a complete novice; I hope you can give me some guidance. Is there a missing parameter?
It’s easy to choose； A centrifugal clean water pump with a flow rate of 30 m3 per hour and a head of 30 to 40 meters will suffice
What are the power of the pump and its operating pressure? Also, how do you calculate the outlet pressure and outlet velocity of a pipe?
Search on Baidu for the website of a centrifugal pump supplier; they all have model specifications, and by checking there you can find information on flow rate and head, as well as details regarding power requirements
