WebJul 20, 2024 · The flow rate is based upon some key factors. Two of the key factors are: The flow rate of water from a pipe (gpm) is based upon the pressure at the source that supplies the pipe. A water pipes resistance to the flow of water is another factor. Note that different water pipe materials have different resistance levels to the flow of water. WebThe liquid outlet velocity when draining a tank or a container can be calculated v = Cv (2 g H )1/2 (1a) where v = outlet velocity (m/s) Cv = velocity coefficient (water 0.97) g = acceleration of gravity (9.81 m/s2) H = height …
