OK. I have figured it out. I build a differential equation, solve it using finite difference. dh/dt = ((2-A2*sqrt(2g*h))/A1

Yes, I also think it's a differential problem, but my teacher wasn't. I don't know why he said that we don't need to use differential equation...he's a professor in quantum physic, expert one, so I still confuse about that...is it true that we don't need it? Is it possible? Still, I can't...

Homework Statement OK, here is my problem. There's a tank, continuously filled by water from top, at 5 L/minute flow rate. The tank has a hole on bottom (at h=0) of it, so water also come out through it. The Area of hole is 1 cm2 and Area of tank is 0.25 m2. The height of the tank supposed...
