Fluid Dynamics

The study of the flow of gases and liquids, usually in and around solid surfaces, is known as fluid dynamics in physics and engineering. Fluid dynamics, for example, can be used to evaluate the movement of air through an airplane wing or the surface of a vehicle. It can also be used in ship design to increase the speed at which ships pass through water.

Question

1. Water is being discharged through a 5-mm diameter hole on the side and lowermost
portion of a full 200-liter cylindrical tank with a height of 1 meter. Determine the initial
velocity of the water jet as it is ejected from the tank.
2. A hot air balloon is filled with heated air and weighs only about one-half of what air
weighs under identical conditions. The buoyancy force, which can be expressed as
Fp= PairgVbaloon
will push the balloon upward. If the balloon has a diameter of 10 m and
carries a 70 kg person, determine the acceleration of the balloon when it is first released.
Assume the density of air is 1.16 kg/m³, and neglect the weight of the ropes and the cage.
