Hello everybody. Ive got some questions.
As the title states: Draining a shaped container from the top, and the amount of Joule it takes to do it. That is what the questions are about.
I did make the first one, and some attempts at the sphere questions b, and c. I left them out because i want to see what you guys come up with. I think ive got the right answers, but we will see if our answers compare. :)
The Dutch text translated: Calculate in questions a, b, and c the amount of work (joule, J) it takes to drain a tank filled with water from the top with a pump. Each question has a discription of the shape of the tank. Take for gravity g=9.81m/s^2. For water take rho=1000kg/m^3.
A coneshaped tank, the topangle is down, with a height of 2.0meters and a radius of 0.5meters.
A sphere with a radius of 1.0meters.
The lower half of a sphere with a radius 2.0meters.
