As shown in the figure, water flows through the pipe with turbulent flow. The volumetric flow rate of water is 0.90ft3/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 hc=4gcVB2f+.lbf/lbbm 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. water=0.036lb/mm3 mercury=0.49lbm/in3
