Hi Everyone, First time posting here...pretty cool forum. Anyway, here is what I am looking at in nonspecific terms. I need to design a tank (non-specific aluminum material that is holding water at room temperature) that is approximately 2.5 feet (must be round) in diameter and 1.5 feet tall (holds about 50 gallons). There must be a hole in the bottom of the tank no bigger than 1.5 inches with a tube leading out of this hole that extends 1.25 inches below the bottom of the tank. The center of this hole must also be 7 inches in towards the center radius from the outside of the tank. What is the fastest way to get 35 gallons out of this tank? Should i put a tube with a chamfer on the side? A cone? A tube on the inside of the tank with a cone? Just a tube on the inside leading to the 1.5 inch hole with a chamfer? Basically, in nonspecific number terms how would you modify the inside of this tank to get the water out as fast as possible? Thanks for all the help.
