 December 20, 2000, 07:37 Water flow into boat #1 GusP Guest   Posts: n/a Being a recreational fisherman, I have the following question. How much water would flow (gal per second) into a boat, if it had a 1" square hole in the bottom and the bottom is 18" under water? What I'm trying to do is to size bilge pump capacity. Could you provide the formula and constants that determine the results. Thank you in advance.
