As shown in the figure, water flows through the pipe with turbulent flow. The volumetric flow rate of water is 0.90 ft3 /s. Water enters in a 4-in Schedule 40 standard steel pipe at point A. The pressure at point C is 24.7 psia. Neglect the pressure drop due to friction. If the sudden contraction loss is

= ^{^2} / ft.lbf/lbm based on the velocity at point B

a) Calculate PB and PA in psia unit, respectively.

b) Calculate the linear velocity at point A.

c) Calculate the linear velocity at point B by writing mechanical energy balance between point A and point B. d) Determine the pipe diameter at point B.
