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

(a) Water flows through a horizontal pipe line of varying cross-section. At a point
where the pressure of water is 0.5 m of mercury, the velocity of flow is 0.25 m/s.
Calculate the pressure at another point where velocity of flow is 0.4 m/s. Density of
water = 10° kg/m³.
Q.No.4.
Derive Euler's equation of motion. How will you obtain Bernoulli's equation from
it?
(c) Write notes on (i) Equation of continuity and (ii) Newtonian and Non-Newtonian

A tripod holding a nozzle, which directs a 5-cmdiameter stream of water from a hose, is shown. The nozzle mass is 10 kg when filled with water. The tripod is rated to provide 1800 N of holding force. A firefighter was standing 60 cm behind the nozzle and was hit by the nozzle when the tripod suddenly failed and released the nozzle. You have been hired as an accident reconstructionist and, after testing the tripod, have determined that as water flow rate increased, it did collapse at 1800 N. In your final report you must state the water velocity and the flow rate consistent with the failure and the nozzle velocity when it hit the firefighter. For simplicity, ignore pressure and momentum effects in the upstream portion of the hose
