Question

We have a tank (large enough to neglect the velocity of the fluid surface in the tank v1 =0). The tank contains water at a mevel of 15 meters. The tank is enclosed and the air space above the water is at 5 atm. The exit of the tank consists of 25 meters of 2 cm diamter pipe with d/D = 0.0004. It exhaust to the atmospere at 1 atm. What is the exit velocity?

Expert Solution

Step 1: Given:

The fluid surface velocity: $rightwards arrow v subscript 1 equals 0 space m divided by s$

The pressure at the surface of water $rightwards arrow P subscript 1 equals 5 space a t m equals 5.013 cross times 10 to the power of 5 space end exponent P a$

Water level difference between the water surface in the tank and exit of the pipe: $rightwards arrow z subscript 1 minus z subscript 2 equals 15 space m$

Final or atmospheric pressure $rightwards arrow P subscript 2 equals 1 space a t m equals 1.013 cross times 10 to the power of 5 space P a$
