Exercise in mathmatics, figure this!

Post  Thesci3141 on Sat Jan 08, 2011 2:50 pm

Hello, A friend of mine and I used to pose questions to each other. The stipulations were: You can't look up anything as far as density's etc. The only things we could use to calculate the answers were : paper and pen and calculator. Here are two of the problems. 1. You have a container holding 1 cubic mile of water. You drain it at the rate of 100 gallons per second. How long does it take to drain all the water? 2. I build a spherical tank of mild steel one inch thick to hold 1-million gallons of water.A. what is the inside diameter of the tank? B. How much does the tank weigh when empty? Easy ? Remember, You have to know the densitys of the mild steel and water off the top of your head. You can't look this up or ask anyone. TEST YOUR KNOWLEDGE!
