hello,

I'm looking for the flow rate equation for the following situation. The stopper rod covers the hole, but when opening has an exponential flow rate. I dont have any values as of now but when I do get them I would like to be able to just plug them into the equation and get results. If there is anyone who could help me it will be great. The equation for a flow rate through a pipe is Q=VA
Q=flow rate
V=fluid velocity
A=cross-sectional area
The hole that the stopper rod covers leads to a pipe. The stopper rod will not raise above 85 mm. Thanks for the help.
