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.

Find an expression for the velocity of water leaving the sprinkler. Find an expression for the gauge pressure at point A, a distance L1, upstream of the narrow pipes. Express the answer in terms of the flowrate, Q. The inner diameter of the first segment of the pipe is d1=10mm, the inner diameter of the second set of pipes is d2=1mm, with N=25. The flowrate through the sprinkler is Q=0.2 L/s. Flow in pipes typically becomes turbulent when the Reynolds number exceeds 2000. Comment on the accuracy of the assumption that the flow could be treated as laminar everywhere. May be assumed water has a density of 1000kg/m^3 and a viscosity of 1mPa s.
A vertical pipe is shown in figure 1 below. The pipe tapers from 50 mm in diameter to 25 mm in diameter. If 2 liters of water per minute flow upwards through the pipe the pressure difference across the pipe is 35 kpa. Calculate the flow downwards through the pipe if the pressure across the pipe is to be zero. The losses across the pipe are given by h1=k((v2) ²-(v1)²)/2g,where v1 and v2 are the velocities in the 50 mm and the 25 mm sections respectively.
