Consider a tank of height 20m filled with liquid of density 100kg/m3. The area of tank is 10m2. If the tank has a hole of area 2m2 at the bottom, find the speed of the liquid flowing out through the hole when the height of liquid in the tank is 10m . Assume speed of liquid descending at top of tank is 5m/s.
