The water from a pipe flows into a tank of volume 180 m3. If the tank is initially empty, how long will it take to fill the tank?
The Attempt at a Solution
This question is the third question from a 3 part problem. In the first two part they were asking me to find the velocity of position 2 of the pipe which is 22m/s, in the second part they were asking me for the diameter of position 2 in the pipe which is 48 cm and in this third part they are asking me how long does it take to fill in the tank with 180 m3.
My attempt was using volumetric flow, but which end should I use? v1a1 or v2a2 since they don't mention where is the tank located at.
any hints to where to start from?
