Water transfer seems like it calls for a measurement of flowrate. So the real question is: how fast is the water flowing through a pipe of that diameter?

- TeMPOraL 11y agoDoesn't that depend on pressure as well?
- JorgeGT 11y agoYes. As a first approximation we can use Bernoulli equation, which states that 0.5V^2+gz+p/rho [1] remains constant through a streamline. If we assume incompressible flow, no friction, perfect discharge, no altitude change etc., and that speed in the pressurized reservoir is null, we can obtain that p_reservoir = 0.5 V^2+p_ambient and thus V = sqrt(2(p_reservoir - p_ambient)) if I'm not mistaken. --- [1] Where V=velocity, g=gravity accel., z=height, p = pressure, rho=density
