Question One Crude oil of specific gravity 0.85 flows upwards at a volume rate of flow of 60 liters per second through a vertical venturimeter with an inlet diameter of 200 mm and a throat diameter of 100 mm. The co-efficient of discharge of the venturimeter is 0.98. The vertical distance between the pressure tapping is 300 mm. 1- If two pressure gauges are connected at the tapping such that they are positioned at the levels of their corresponding tapping points, determine the difference of readings in N/cm² of the two pressure gauges. 2- If a mercury differential manometer is connected, in place of pressure gauges, to the tapping such that the connecting tube up to mercury are filled with oil, determine the difference in the level of the mercury column. uestion Two ( Its required to pump a liquid of specific gravity (1.26) and dynamic the rate of (22) jiters per second from a sump tank and 2 M

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.
