How do you calculate the thickness or gauge of a given metal (304 Stainless Steel for example) for a 36" dia. round, vertical cylinder water holding tank? If filled say the tank would be 25-30 feet tall. No physical pressure (pumps or vacuum) on this vessel (vented to atmosphere). Flat...

Thank you for any help that you can give me. I am very bad at differential equations and this one is really stumping me. Homework Statement A tank contains 2740 L of pure water. A solution that contains 0.05 kg of sugar per liter enters a tank at the rate 3 L/min The solution is mixed and...

Heat loss from an insulated water tank ----- Thermodynamics Hi and thanks in advance for any help with this problem. If I have a very very well insulated tank of water of say 4 litres. If we could assume that the tank had no heat loss... The tank is heated by an electrical device that...

Homework Statement A tank of height h full of water with it's base 40 meters from the ground, with a hole on the lateral wall at the base. The water comes out of the tank at 6.93 m/s to fill a pool on the ground. The water hits the center of the pool at a distance of 19.5 meters measured...

Homework Statement The amount of water in a storage tank, in gallons, is modeled by a continuous function on the time interval 0<=t<=7, where t is measured in hours. In this model, rates are give as: (i)The rate at which water enters the tank is f(t)=100t^2*sin(sqrt(t)) (ii) The rate at...

Homework Statement A water tank of height h has a small hole at height y. The water is replenished to keep h from changing. The water squirting from the hole has range x. The range approaches zero as y goes to 0 because the water squirts right onto the table. The range also approaches zero as...
