Fluid mechanics, jet problem:

The balloon rocket is held in place by a force, F. The pressure inside the balloon is 8 in-H_{2}O, the nozzle diameter is 1.0 cm, and the air density is 1.2 kg/m^{3}. Find the exit velocity, v and the force, F. Neglect friction and assume the air flow is inviscid and irrotational.

Step 1

**To determine**: The exit velocity, v and the force F.

Step 2

The pressure inside the balloon is 8 in-H_{2}O.

Air density is 1.2kg/m^{3}

The diameter of the nozzle, d is 1.0 cm

Step 3

**Calculation:**

The figure is shown...
