Exp. (6): Flow Over Weirs Purpose: * To demonstrate the characteristics of flow over weirs. * To determine the ’Coefficient of Discharge’ for each type of weir. Introduction: In open channel hydraulics‚ weirs are commonly used to either regulate or to measure the volumetric flow rate. They are of particular use in large scale situations such as irrigation schemes‚ canals and rivers. For small scale applications‚ weirs are often referred to as notches and invariably are sharp edged

PrFan Blades Rolls Royce is unique for its patented manufacturing process of its hollow wide-chord titanium fan blades. To make these fan blades light and strong the fan blades are made from titanium 6-4 alloy with a hollow internal “Warren–Girder” structure. This is done using 2 processes namely Superplastic forming and Diffusion bonding. The manufacture process starts with 3 sheets of forged titanium. A material called stop-off is printed onto 2 of the sheets which will stop them from joining

ABRASIVE JET MACHINING INTRODUCTION:- IT IS A PROCESS OF MATERIAL REMOVAL THROUGH THE ACTION OF A FOCUSED STREAM OF FLUID WITH ABRASIVE PARTICLES. IT IS ESPECIALLY USED FOR MACHINING SUPER ALLOYS‚ CERAMICS; GLASS AND REFRACTORY MATERIAL. IT IS ONE OF THE NON-POLLUTING METHODS AVAILABLE FOR MACHINING HARD MATERIALS TO PRECISION DETAILS. IN ABRASIVE WATER JET MACHINING THE ABRASIVE PARTICLES UTILIZES WATER JETS TO ACCELERATE OR DECELERATE THEIR SPEEDS DEPENDING UPON THE TYPE OF MATERIAL TO BE MACHINED

tan colored sand‚ I think to myself‚ “This is perfect.” I make the final preparations on my jet ski. All of the fluid levels check full and there is a faint smell of gasoline mixed with the aromas of salt and fish in the air. I am now ready to brave and jump the mighty ocean waves of South Padre Island! Before the truck backs the trailer into the warm waters at the dock and lowers the Jet Ski into the blue-green abyss‚ I crank the engine for a final systems check. It roars powerfully‚ drowning
