Question: Water ( SG = 1 ) flows at a rate of 0 . 0 4 0 m 3 / s in a 0 . 1

Water (SG =1) flows at a rate of 0.040 m 3
/s in a 0.12-m-diameter pipe that contains a
sudden contraction to a 0.06-m-diameter pipe. Determine the pressure drop across the contraction
section. How much of this pressure difference is due to losses and how much is due to kinetic
energy changes?
