Water is fed via a 200m long, 125mm diameter pipe to a field. The take is 12m elevation. the friction factor is 0.008 and k factors add up to 3.3. Pressure is all atmospheric and V1 is 0. 2. Relevant equations Bernoulli Equation with the addition of friction, elevation and k factors 3. The attempt at a solution V^2(2) = 2g+Z(2)+4f l/d + k I have managed to find around 4 different equations and think they are all wrong. I have excluded parts of the equation as they are equal to zero on boths parts of equation. What i need to do is solve V(2) and obtain the mass flow rate? Help is very much appreciated.
