Consider water flow in a piping network. The pressure, velocity, and elevation at a specified point (point 1) of the flow are 300 kPa, 2.4 m/s, and 5 m. The velocity and elevation at point 2 are 1.9 m/s and 18 m, respectively. Take the correction factor to be 1. If the irreversible head loss between point 1 and point 2 of the pipe is 2 m, the pressure of water at point 2 is (a) 286 kPa (b) 230 kPa (c) 179 kPa (d) 154 kPa (e) 101 kPa

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.
