Hi All,
I'm trying to solve this problem about a tank draining:
A 3 inch diameter orifice on the side of a 5 ft diameter tank draws the surface down from 7 ft to 5 ft above the orifice in 53 seconds. Calculate the discharge coefficient.
I started using the equation Q = C A sqrt 2gh, but the solution manual shows a different equation using time. I don't see that equation anywhere in the PE formula handbook and don't know how I could even derive that! so I'm wondering is there another way I can solve this?
If anyone can please explain, please let me know! Thanks
(p.s. the answer is supposed to be C = 0.77)
