A service main (water pipe) at the end of a street decreases in diameter from 8 inches to 4 inches. The flowrate is 5 ft3/s and the pressure at point 1 is 50 psi. Neglect losses. a. Find the velocity at point 2 in ft/s. b. Calculate the pressure at point 2 in psi. c. Compare the pressure in the wider pipe with the pressure in the narrow pipe. Is it what you would expect?(1)8″-diameter4″-diameter(2)10 ft
