negligible loses‚ 3 standard flanged 90 smooth elbows (KL = 0.3 each)‚ and a sharp-edged exit (KL = 1.0). We choose points 1 and 2 at the free surfaces of the river and the tank‚ respectively. We note that the fluid at both points is open to the atmosphere (and thus P1 = P2 = Patm)‚ and the fluid velocity is 6 ft/s at point 1 and zero at point 2 (V1 = 6 ft/s and V2 =0). We take the free surface of the river as the reference level (z1 = 0). Then the energy equation for a control volume between these two

Pressure Management on a supercritical aerofoil in transonic flow Abstract-At transonic speeds an aerofoil will have flow accelerate onwards from the leading edge to sonic speeds and produce a shockwave over the surface of its body. One factor that determines the shockwave location is the flow speed. However‚ the shape of an aerofoil also has an influence. The experiment conducted compared Mach flow over a supercritical aerofoil (flattened upper surface) and a naca0012 aerofoil (symmetrical).

FALL 2012 ME 305 FLUID MECHANICS I EXPERIMENT 1 MEASUREMENT OF FLUID PROPERTIES PREPARATION: In this course‚ you will conduct the experiments at the Fluid Mechanics Laboratory‚ by yourselves‚ without any help or instruction from the teaching assistants. You must read the lab sheet thoroughly and understand what you are expected to do (and why) for each experiment‚ before coming to the lab. At the end of each experiment‚ you will have to do certain calculations‚ present and plot (when asked)

MEASURING AND MODELLING HYDRAULIC FLUID DYNAMICS AT HIGH PRESSURE - ACCURATE AND SIMPLE APPROACH. International Journal Of Fluid Power‚ 13(2)‚ 51-59. ASTRACT: Dynamic properties of hydraulic fluids have to be taken into account in ever increasing fluid power applications. The main reasons are increasing accuracy demands in control and modeling‚ as well as increasing operating pressure and temperature ranges. Moreover‚ the already wide spectrum of different hydraulic fluids is also expanding all the time

FLUID MECHANICS Fluids mechanics is a branch of mechanics that is concerned with properties of gases and liquids. Mechanics is important as all physical activities involves fluid environments‚ be it air‚ water or a combination of both. The type of fluid environment we experience impacts on performance. Flotation The ability to maintain a stationary on the surface of the water- varies from he on person to another. Our body floats on water when forces created by its weight are matched equally

Lecture No. 5 CLASSIFICATION OF FLUID FLOW AND THE CONTINUITY EQUATION 5.1 Classification of Fluid Flow Uniform flow If the velocity of the fluid is the same in magnitude and direction at every point in the fluid the flow is said to be uniform. Non-uniform flow A non-uniform flow is one where the velocities at different points at a given instant are not the same. Every fluid that flows near a solid boundary will be non-uniform because the fluid at the boundary takes the velocity of the

CEIC2001 – Fluid Mechanics Notes Fluid – A substance which is capable of flowing. A fluid is also a substance which has no permanent resistance to change in shape i.e. a solid can resist a shear stress‚ τ by static deflection; a fluid cannot‚ any shear stress applied to a fluid will result in the motion of that fluid for as long as the shear stress is applied. τ=FA Where F = force which is tangent to a surface (shear force)‚ A = area of moving plate in which shear force is applied to.

of the drag force on a circular cylinder. The devices used in this experiment were a fan‚ closed-channel venturi-shape pipe‚ a Pitot tube‚ circular cylinder with holes of different angles‚ U-tube manometers and a barometer. INTRODUCTION When a fluid is passing through an object‚ it produces a total force on the object. This force is a combined force of lift and drag forces (Anderson 2007). External flows past objects have been studied extensively because of their many practical applications. For
