At location 2 the pipe diameter is 17.7 cm. At location 1 the pipe is 9.33 m higher than it is at location 2.

Explanation / Answer


A1 = p1*r1^2


A2 = pi*r2^2


from equation of continuity

A1*v1 = A2*v2


v2 = A1*v1/A2


v2 = (11.5/17.7)^2*9.25 = 3.904 cm /s

P1 + 0.5*rho*v1^2 + rho*g*h = P2 + 0.5*rho*v2^2


P2 - P1 = 0.5*rho*(v1^2 - v2^2) + rho*g*h


P2-P1 = (0.5*1350*((0.0925*0.0925)-(0.03904*0.03904))) + (1350*9.8*9.33)


P2 - P1 = 123440.65 Pa <------------answer


P2 - P1 = 123.44065 Kpa
