Water is flow in a 4 in Schedule 40 steel pipe at 20oC and 1 atm. Orifice meter with orifice diameter 6.2 cm is fitted in pipe to the horizontal to measure the flow rate of water. The difference in manometer head is 5 cm of mercury. Expansion factor can be taken as 1. a) Calculate the volumetric flow rate of water. b) What would be the throttle diameter of venturi meter if a venturi meter was used in a system where the flow rate is 4 m/s and pressure drop is the same in part (a). Note: Be sure to check your assumption for orifice and venturi meter constants

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.
