Problem 1(4.34. page 184) Water is flowing in a 2.5 in. diameter pipe at 60 ft/sec. If the pipe enlarges to a diameter of 5 in., calculate the reduced velocity. Also, calculate the mass flux and the flow rate. Equations: Solution:
Problem 2(4.36. page 184) A pipe transports 200 kg/s of water and the pipe tees into a 5 cm dia. Pipe and a 7 cm pipe. If the average velocity is 25 m/s in the smaller pipe calculate the flow rate in the larger pipe. Equation: Solution:

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:...
