Problem 9 Determine the pressure drop across a 90 standard elbow in a DN 65 Schedule 40 steel pipe if water at 15C is flowing at the rate of 750 L/min. Problem 10 Consider the portion of a hydraulic circuit shown below. The pressure at point B must be 200 psig when the volume flow rate is 60 gal/min. The hydraulic fluid has a specific gravity of 0.90 and a dynamic viscosity of 6.0 x 105 lb-s/ft. The total length of pipe between A and B is 50 ft. The elbows are standard. Calculate the pressure at the outlet of the pump at A. 2-in Schedule 40 steel pipe B Flow Control 25ft valve K=6.5 Pump
