Unformatted text preview: Water is 4mdeep behind a gate in a rectangular channel and is suddenly open find initial dh/dt if V2=8m/sec V1=.2m/sec and the channel length is 100m. Equations: Solution: Problem 6(4.74. page 189) Find V1 in the vertical pipe Equations: Solution: Problem 7(4.79. page 189) Predict the value of H and p Equations:, change in pressure = 19998.4 pa We know as the height in mercury decreases the pressure at the 10 cm diameter is decreasing the 20 cm value will give u higher pressure and H than 15 cm Problem 8(4.82. page 190) Calculate flow rate on section A. Equations: Solution: a) b) Continued c) Problem 9(4.91. page 191) When will the siphon cease to function At 3m the siphon will cease to lose suction because it will be too height to do so. Problem 10(4.99. page 191) Velocity in pipe =10 m/s a is K=1.5 b to c is k=6.2 and the pump is 80% efficient if pc =200 kpa find pa and pb. Equation: Solution:...
