Homework Statement
What gauge pressure is requried for water in a water supply line to reach a vertical height of 15m?
Homework Equations
Bernoulli Equation
The Attempt at a Solution
I have tried this numerical by taking velocity at ground level to be equal to velocity at top i.e. 15m height. The answer is correct as given in the textbook but I am not convinced by this technique. I wonder how can water have same speed at bottom and top? (Sorry I know no way to add image to PF, that is why I cannot add my work to show how I calculated it.)
