Question

Saturated water at 25C enters a tank through a 10-cm diameter pipe at a velocity of 3 m/s. At the bottom of the tank, water exits at 6 m/s through a 5.25- cm diameter pipe. The depth of the water in the tank is 1.5 m. The tank has a diameter of 1.25 m and a height of 2.5 m. Water in the tank is also magically kept at 25C, which is the same to the surrounding temperature. Assume that pressures at inlet, outlet, and the surrounding are roughly the same and pressure effect is negligible.

Answer 1

see answer attached

Step-by-step explanation:

That velocity for part b should be 3 m/s and I have calculated the potential energy with respect to the base of the tank.
