Water is flowing steadily in a horizontal elbow and nozzle combination shown in the figure. The gage pressure at section (1) is 100 kPa with inlet velocity of 2 m/s. At section (2) the water exits to the atmosphere. Neglecting pipe weight, determine the magnitude and direction of the x and y components reaction forces exerted on the flanges to withstand this flow. 160 mm V2 - y section (2) 300 mm V1. section (1) P, = 100kPa V, = 2m/s

3. [Ch4 - 1] What is the head loss and corresponding pressure drop (in units of bars) across a 30- mm-wide open gate valve when oil (SG = 0.90) flows through at a rate of 4 x 10-3 m/s? 4. [Ch4 – 2] Oil (SG = 0.80, v = 10- m/s) flows at a rate of 2 x 10-3 m'/s through a 20-mm- diameter commercial steel pipe. What is the equivalent length of a 20-mm-half open gate valve placed in the line?
