8gpm.
With the drain closed you would need 2 hours (120mins ) to fill the tub. To fill it in one hour (60 min) you need double that so 2 gpm. In a minute you need 8 gallons so that after draining 6 gallons you still are left with 2 gallons.

If you don't fail now and again, it's a sign you're playing it safe. http://jsridhar.blogspot.com |
