Bernoulli’s Principle states that for an ideal fluid (low speed air is a good approximation)‚ with no work being performed on the fluid‚ an increase in velocity occurs simultaneously with decrease in pressure or a change in the fluid’s gravitational potential energy. This principle is a simplification of Bernoulli’s equation‚ which states that the sum of all forms of energy in a fluid flowing along an enclosed path (a streamline) is the same at any two points in that path. It is named after the

industries used to increase the output of an underground fluid. Fracturing is used to access or augment productivity in petroleum‚ water and natural gas. The actual process is accomplished deep underground when a pressurized fluid is ejected from underground piping into the surrounding rock formations. The pressure of the fluid creates a crack in the rock which continues to expand as the pressure is applied. Solid additives in the pressurized fluid prevent the rupture from resealing once the pressure

Fluid Mechanics CHE2161/MEC2404 Frictional Flow in Pipes Experiment : Friday 8.30-11.30am Conducted In : Fluid Mechanics Lab Abstract The main aim of this experiment was to show how the friction factor varies with Reynolds number by manipulating the flow rate of the fluid in a pipe. The main principle used in the experiment was the Bernoulli’s equation‚ taking major head losses into account. These major head losses were normally due to wall friction in the pipe and viscous

efficient separation technique to be employed for an analysis. 2 What is supercritical fluid? 3 Critical temperature (Tc) for any substance is a temperature above which it can no longer exist as a liquid‚ no matter how much pressure is applied. Critical pressure (Pc) is a pressure above which the substance can no longer exist as a gas no matter how high the temperature is raised. A supercritical fluid is any substance that is above its Tc & Pc [critical point]. CRITICAL POINT In other

FUNDAMENTAL CONCEPTS Heat transfer is energy in transit‚ which occurs as a result of temperature gradient or difference. This temperature difference is thought of as a driving force that causes heat to flow. The concepts of heat transfer and temperature‚ the key words in the discipline of heat transfer‚ are 2 of the most basic concepts of thermodynamics. dffffffffff rifffff orfff ffffffffff fv ing ff ce Rate of transport process= fffffffffff or rate = coefficient B driving force resist

apparatus. Reynolds number for the tests at ∆P=5psi is 5.3913×10-5 and for ∆P= 30 psi is 1.1147×10-4. Laminar flow conditions exist so that Darcy’s equation is applicable. 2.0 Introduction When fluid flows through a medium‚ the flow is affected by the property of the medium that allows the flow of the fluid through it. The property of the medium is called permeability. Permeability

LINE 1. Introduction A Venturi meter is a device for determining the flow-rate of a fluid down a pipe. One measures the pressure difference between the venturi inlet and neck‚ and from this the flow-rate can be determined. The apparatus used on this experiment also has a number of straight tube manometers at equally spaced intervals. These will be used to determine the hydraulic grade line of the fluid as it passes through the manometer. 2. Apparatus and theory of the venturi A diagram
