## Homework Statement

## Homework Equations

Bernoulli equation.

Continuity equation

## The Attempt at a Solution

Area of pipe is constant, so v_a = v_b = v_c = v_d.[/B]

Using point on water surface and point D.

Point on water surface: z = 8, v = 0, P = 0 (P_atm)

Point D: z = -2, P = 0 (P_atm) v = ?

Using Bernoulli, v_d = \sqrt {2*10*g} = 25.4 ft/s

P_a = -4018.56 psi

P_b = -20092.8 psi

P_c = -24111.36 psi

All are gauge pressures. Since they are all negative, I am not sure if I am doing something wrong?
