A 2cm dismeter faucet tap fills a 2.5 x 10^-2 m^3 container in 30 sec. What is teh speet at which the water at which the water leaves the faucet?
I know the continuity equation. where (area1)(velocity1) = (area2)(velocity2). and the volume flow rate = area x velocity. I also know Bernovlli's equation where P1 + .5(density)(velocity1)^2 +(density)(9,8)(y1) = P2 + .5(density)(velocity2)^2 + density)(9,8)(y2).
I am trying please not to cheat. But I don't know how to work this out. Please help me. thx a lot I appreciate it so much.

calculate the volume flow rate (fills the volume of the container in 30 sec)
pushing that flow rate through the area of the faucet will give you the speed
