Question

A horizontal water pipe is reduced in size from 18 inches in diameter from point A to 6 inches in diameter to point B. The flow in the pipe is 10 cubic feet per second, and the pressure in A is 20 psi (gage). If it is assumed that there is no less energy due to friction, what is the pressure at B?

(Problem 3) A horizontal water pipe is reduced in size from 18 inches in diameter
from point A to 6 inches in diameter to point B. The flow in the pipe is 10 cubic
feet per second, and the pressure in A is 20 psi (gage). If it is assumed that there
is no less energy due to friction, what is the pressure at B? *
