Will somebody help me how to calculate the amount of force and internal pressure acting on a 90 degree elbow located 2 ft. from a ball valve? The piping system is a by pass line of a high pressure loop. The line before the ball valve is @ 1,000 psi, 40 ft. total distance,4" dia. 316 SS sch 80 pipe conveying water at 80 deg. F at velocity of 15 ft./sec. and discharges to atmospheric pressure. The elbow as stated is located 2 ft. downstream of the ball valve.
Any help on formula to be used or reference on the subject is highly appreciated.
