February 1, 2021 Q1 (35 pts.) Water flows at a horizontal elbow nozzle combination with a discharge of Q = 0.1 m3/s. The pressure at section 1 is measured as 100 kPa. Determine the force necessary to hold this pipe combination in its place. (Di= 500 mm, D2= 250 mm) Section (2) V2 1 D D 1 V; Section (1) Q2 (30 pts.) A plane gate of uniform thickness holds back a depth of water as shown. Find the minimum weight needed to keep the gate closed.
