WebDec 2, 2024 · In general in the Fire Service we are taught that if you increase the presure of water coming out of our pumps you will also increase the flow rate ie ammount of water. We recently discovered in the manurfactures guidance that our pump is capable of delivering a much higher flow rate at a lower pressure. Our pump can deliver 800 litres per ... WebApr 14, 2014 · The relationship between flow, velocity, and pressure can be explained using Bernoulli’s principle. Bernoulli’s equation states mathematically that if a fluid is flowing through a tube and the tube diameter decreases, then the velocity of the fluid increases, the pressure decreases, and the mass flow (and therefore volumetric flow) remains …
