1, Problem Statement.
A resevoir releases water into a 2 meter diameter drain pipe that is 200 m long with a 5ο gradient drop. Assume pipe is full without friction. If v0 is zero what is velocity at 200 meter discharge ?
And what is the pressure in atm ? The height at pipe end is - 17 meters. A 17 m drop from resevoir to end of 200 meter pipe
For vertical time , y = 1/2 at2 = 1,86 sec
For vertical velocity vy = v = √2ay = 18m/sec
Pressure = Force/Area = mass*acc/area = 628000 kg * 9,8m/sec2/3.14 m2
Pressure = p0 + ρ h g
Assume water density = 1
Sine 50 = .087. = 18m/s/v = 204m/sec ? or is it sine 50 (18m/s) = 1.5m/sec ?
Not sure about pressure formula to atm
All I am looking for are the equations for velocity and pressure at pipe exit from above data. http://www.calctool.org/CALC/eng/civil/hazen-williams_g
