Hello,
Am the owner of a 90 acre man made lake and am trying to calculate the flow out of 12 inch pipe at the bottom of the lake. The lake is approximately 10 feet deep. Can someone point me in the right direction on how to solve this question?

Hello Caerus1! Welcome to PF! :smile:

If it's a real pipe, it's probably blocked, but the theoretical speed is √(2gh/ρ), where g is 9.81 cm/sec2, h is the difference in height between the surface of the lake and the far end of the pipe, and ρ is the density of water. :wink:
