1. Identify each of the following statements as either true or false. If false‚ explain why. (a) Viscosity is a measure of how easily a fluid flows. (b) Although important‚ fluids are not essential to many living things. (c) A meniscus forms when water particles adhere to the sides of their container. (d) Buoyancy‚ like water pressure‚ acts in all directions. 2. Describe the relationship between mass‚ volume‚ and density of matter. 3. Use the particle theory to explain the differences between

Fluid Report 2 In the derivation of Bernoulli’s equation‚ the assumption of the inviscid and incompressible flow is used. However in the real case‚ the viscosity cannot be neglect and the density of the flow is not always constant. Thus Bernoulli’s equation is not always correct. For the lab‚ it is reasonable to assume the flow is inviscid and incompressible. Firstly‚ the pitot was placed at the center of the flow. The skin friction (effect of viscosity) is inversely proportional to distance

Report: Pipe Friction MODULE LEADER: Dr. MEHDI NAZARINIA 1. Introduction The flow of fluid in a pipe under pressure is used to reach many goals. A good knowledge of the fluid flow and pipe pressure at some point along the path of the pipe may facilitate to determine the size‚ capacity and material of the pipe for a system. In engineering and industry‚ the understanding of pipe flow is required for the control‚ transport‚ measure and storage of water or other fluids.

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

Fluid mechanics is the branch of physics that studies fluids (liquids‚ gases‚ and plasmas) and the forces on them. Fluid mechanics can be divided into 1) fluid statics‚ the study of fluids at rest; 2) fluid kinematics‚ the study of fluids in motion; 3) fluid dynamics‚ the study of the effect of forces on fluid motion. Fluid Mechanics Overview Fluid is a substance that is capable of flowing. It has no definite shape of its own. It assumes the shape of its container. Liquids and gases are

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
