How fast would water go if at the end of of a 1 inch diameter pipe was closed by a valve? The system is as follows:
5 meter high source of water that feeds a 1 in pipe. The pipe goes straight down from the middle of a 25 square meter box. (1 high x 5 wide x 5 deep)
At the end of of the pipe, a valve is attached.
The valve is opened instantly.
So far I have worked out the velocity of the water as if there were no blockage.
$v = (2gh)^{1/2}$
$v = 9.9 m/sec$
Does the presence of the blockage change the velocity of the system when it is removed? Diagram:
