Both types of pumps "create flow". Do both create pressure, no. Pressure is the resistance to flow. Pumps distribute their added energy into a system. Hydraulic energy can be represented by Pressure x Flow. Therefore the practical answer is pumps distribute energy into the system that results in both pressure and flow. If Energy added into the system by the pump is limited by the motor size and its efficiency to 1kW, power is Energy per unit time, 1kW/second, or 1000 Nm/s, or 1000 W/s is added into the system, then we can assume that pressure x flow = 1000. P x F = E. Just looking at 1 second, Energy is 1000 Nm. So the pump will make an energy distribution of 1000. Pressure is potential energy and flow is kinetic energy. We will get some combination of that which equals 1000. If pipe and equipment resistance to flow is high, we will get a low flow, kinetic energy expended will be low, say 100. Since P x F =1000, that leaves P x 100 = 1000. Solving for P, P= 1000/10 =10, a pressure of 10 results. If flow resistance is low, say 5, kinetic energy expended can be high. How high? P x 5 = 1000, so solving for potential energy, P =1000/5= 20. The pump creates flow, the pipe system resists flow. How much flow the pump creates is determined by subtracting flow resistance of the system, kinetic energy, from motor energy added to the system, and whatever remains is pressure, the potential energy.

i have 2 wind blowers there is written PSI and i have one other there is written RPM. what is the difference

What happens to the readings of pressure and current indicators and the amount of water pumped when a break occurs on the main water line of the city network?

Hello sir can you explain is water turbine require water flow or water pressure

HI! I have a simple doubt: if at the delivery point my pressure is fixed (a huge pressurized reservoir, for exemple) and I increase the flowrate, what would happen at the pump discharge? Since flow is higher, but delivery pressure is fixed, the pressure at discharge would get low?

Pressure and Flow for a pump is quite confusing with Bernoulli's equations 😢

to be honest I came here to a have better explanation for my computer Pump
