Buoyancy is an upward force exerted by a fluid that opposes the weight of an immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus a column of fluid, or an object submerged in the fluid, experiences greater pressure at the bottom of the column than at the top. This difference in pressure results in a net force that tends to accelerate an object upwards. Explanation: The ability or tendency to float in water or other fluid

I. INTRODUCTION Viscosity, η, is the resistance of a fluid to flow. The units of viscosity could be poise, dyne-seccm2, gcm-s, N-sm2 or Pa-s. Determination of the viscosity of a fluid is done by measuring the time of flow of a given volume of (V) of the liquid through a capillary tube under the influence of gravity. There are generally 3 types of viscometers for this capillary flow method–the Ostwald Cannon-Fenske, and the Ubbelohde viscometers. The flow is governed by the Hagen-Poiseulle Equation:

~~~Concept of Wind-tunnel~~~ Wind tunnels date back to the 1870’s. Scientists realized it didn’t matter if an object was stationary and air was blown was over the object or if the object was moving through the air. The resultant forces over the object would be the same. The idea of blowing air over an object and determining the forces lead to the invention of wind tunnel. As the name suggests, a wind-tunnel is a cylindrical tunnel in which air is blown from one side by a huge fan at high

Fluids Lab Viscous Losses in Pipes Objectives: Compare the flow rate/pressure drop characteristics for flow in pipes in the laminar and turbulent regions. Apparatus: The experiment is conducted with the help of a Manometer, with which the pressure drop between two gauge points can be measured. For small pressure differences the water (oil) / air manometer is used, whereas for larger pressure differences the mercury / water (oil) manometer is used. The flow rate of the water is measured in

Fundamentals of Fluid Mechanics Fluid mechanics is the study of fluids and the forces on them. (Fluids include liquids, gases, and plasmas.) Fluid mechanics can be divided into fluid kinematics, the study of fluid motion, and fluid dynamics, the study of the effect of forces on fluid motion, which can further be divided into fluid statics, the study of fluids at rest, and fluid kinetics, the study of fluids in motion. Fluid mechanics is very important to engineers when observing flow in pipes

We shall begin by studying incompressible flow problems. Of course all fluids are, to some extent, compressible but under steady flow conditions we may assume that the effects of changes in fluid density are small. In fact, it is the velocity of the fluid that dictates whether changes in density are significant and must be accounted for. In Chapter 6 we shall quantify the velocity limit, below which may assume that the fluid is incompressible; however, the majority of fluid flow problems
