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. A reversing elbow used to deflect water flow at a rate of 14 kg/s in a horizontal pipe to make
a U-turn before it is discharged into the atmosphere, as shown in Figure 1. The cross-section
area of the elbow is 113 cm² at the inlet and 7 cm² at the outlet. The elevation difference
between the centers of the outlet and inlet is 30 cm. Neglecting the weight of the elbow and
the water in it and assuming the flow is frictionless, determine the anchoring force needed to
hold the elbow in place.
