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

EXPERIMENT 1 – HEAD LOSSES IN PIPES Introduction: In this experiment‚ the aim is to find the losses of water flow in a pipe system.There are two types of losses. First the major losses which is caused by the the frictional effect of pipe. Second one is the minor losses which is caused by the turning points(corners) of pipes. Apparatus: • • • • • • 90° mitter bend 90° elbow bend 90° large radius bend Sudden enlargement in pipe diameter Sudden contraction in pipe diameter A pump to supply water

EFFECT OF SURFACE AREA ON AIR FRICTION Design Background Information: Air resistance‚ also called drag‚ is the forces that are in opposition to the relative motion of an object through the air. Drag forces act opposite to the oncoming flow velocity. Size and shape are the two factors that affect air resistance. Air resistance depends on the surface area‚ so‚ as the surface area increases‚ the air resistance increases. When an object is falling‚ air resistance acts to push it back up. This is

Bore-Out and Burn-Out The desease of the modern workforce Introduction Role-Play Theory Bore-Out Burn-Out Tips and Tricks Bore-Out History For years‚ it was always just about the burnout - the excessive demands. Now it has been recognized that even under load‚ called bore out‚ can make you sick. The bore out syndrome is primarily a phenomenon of the service economy. A craftsman can not pretend that he would work. In professions where you have to deliver results bore out hardly occurs

Static Friction INTRODUCTION When an object is placed on a surface it will remain static unless the resolved component of the force due to gravity acting parallel to the surface exceeds the friction force associated with the static coefficient of friction between surfaces by placing various objects on a surface and tilting the surface until the object begins to slip. By measuring the angle at which the object begins to slip‚ it is then possible to calculate the coefficient of friction between

following terms: a. Pressure Head pressure head [′presh·ər ‚hed] (fluid mechanics) Also known as head. The height of a column of fluid necessary to develop a specific pressure. The pressure of water at a given point in a pipe arising from the pressure in it. b. Total Discharge Head Total discharge head refers to the actual physical difference in height between the liquid level in the pit and the highest point of the discharge pipe or water level in the outlet. c. NPSH Net Positive Suction Head

ABSTRACT The quality of pipe borne water supplied by Imo State Water Corporation has been assessed by analyzing samples of water collected from different locations for their physicochemical parameters and bacteriological quality. The observed values were compared with standard values given by the World Health Organization for potable water .The quality of the analyzed water is found fit for human consumption.

Justice to the Original: Smooth Talk and Where Are You Going‚ Where Have You Been? Ideas for the story lines of many motion pictures get their inspiration from other works of writing often. Books are usually a main source of inspiration for movies‚ for instance‚ the movie Smooth Talk was based off of Joyce Carol Oates’ short story Where Are You Going‚ Where Have You Been?. Most of the time however‚ you hear that the movie did not give justice to the book. Smooth Talk is an exception to this
