Fluid mechanics VIVA QUESTIONS and ANSWERS

1. Define density? Ans: It is defined as the ratio of mass per unit volume of the fluid. 2. Define viscosity? Ans: It is defined as the property of fluid which offers resistance to the movement of fluid over another adjacent layer of the fluid. 3. Differentiate between real fluids and ideal fluids? Ans: A fluid, which is in-compressible and is having no viscosity, is known as ideal fluid while the fluid, which possesses viscosity, is known as real fluid. 4. What is a venturimeter? Ans: It is a device which is used for measuring the rate of flow of fluid flowing through pipe. 5. What is a notch? Ans: A notch is a device used for measuring the rate of flow of a fluid through a small channel or a tank. 6. Define buoyancy? Ans: When a body is immersed in a fluid, an upward force is exerted by the fluid on the body. This upward force is equal to the weight of the fluid displaced by the body. 7. Define meta-centre? Ans: It is defined as the point about which a body

Welding-LAP JOINT

Ex. No : Date : LAP JOINT Aim To join the given two work pieces as a lap joint by arc welding. Material used Mild Steel plates. Tools required Welding power supply Flat file Welding rod Chipping hammer Electrode holder Wire brush Gloves and apron Earthing clamps Shield and goggles Procedure The given workpieces are thoroughly cleaned, i.e. rust, scales are removed and the edges are filed. The electrode is held in an electrode holder and ground clamp is clamped to the welding plates and the power is supplied. The workpieces are positioned on the table to form a “Lab joint”. The tag weld is done on the both the ends of joining plates to avoid the movement of workpieces during welding. The welding is carried throughout the length of the workpieces on both sides by maintaining 3mm gap between plates and the welding rod. The welded plates are allowed f

Welding VIVA question and answers

VIVA QUESTIONS : Q1: Define welding? Ans: Welding is a fabrication process that joins two or more materials, typically metals or thermoplastics, by melting and fusing them together using heat or pressure. Q2: What is the typical thickness of MS Plate used in general welding workshop experiments? Ans: The thickness of the MS (Mild Steel) plate used in general welding workshop experiments can vary depending on the specific requirements of the experiment. However, commonly used thicknesses range from 3 mm to 12 mm. Q3: What is the common job material used in welding experiments? Ans: The common job material used in welding experiments is mild steel. It is widely available, affordable, and relatively easy to work with, making it suitable for various welding applications and practice. Q4: What is the main function of an electrode in welding? Ans: The main function of an electrode in welding is to carry the electric current necessary for the welding process and to provide filler mate

Coordinate systems in AutoCAD

World Coordinate System (WCS), User Coordinate System (UCS). There is 4 AutoCAD coordinates system you should know. Absolute coordinate system , Relative Rectangular coordinate system, Relative Polar coordinate system and Interactive system(Direct coordinate system). Absolute Coordinate system: Absolute Coordinates uses the Cartesian System to specify a position in the X, Y, and (if needed) Z axes to locate a point from the 0-X, 0-Y, and 0-Z (0,0,0) point. To locate a point using the Absolute Coordinate system, type the X-value, Y-value, and, if needed, the Z-value separated by commas (with no spaces). Syn: Enter LINE command: L [Enter] Start line at point A: 0,0 [Enter] End first line at point B: 2,2 [Enter] End of second line at point C: 2,3 [Enter] Examples shown bellow. Relative Rectangular Coordinate system: After first points entered, your next points can be entered by specifying the next coordinate compare/relative f

MOULD WITH SPLIT PATTERN

Ex. No : Date : MOULD WITH SPLIT PATTERN Aim To make the mould for the given split pattern. Material required • Moulding board • Riser pin • Moulding box • Sprue pin • Green sand • Rammer • Trowel • Lifter • Riddle • Draw spike • Gate cutter • Bellow • Vent rod Procedure 1. Place the moulding board on a horizontal surface. 2. The drag box is placed above the moulding board. Now one piece of pattern is kept at center of the drag as shown in figure. 3. The parting sand is spread before we keep the pattern. 4. Facing sand is sprinkled over the pattern to a depth of 2mm. then greensand is filled over it. 5. Proper ramming is done on the green sand to get a air free packing. 6. Excess sand is remove with strike off bar. 7. The drag is inverted upside down. 8. The cope box is place over the drag box. 9.

Sheet metal Funnel making

Making a Funnel using metallic sheet Making a Funnel using metallic sheet Aim:- To make a funnel from a given (GI)metallic sheet. Tools Required:- MALLET, SNIP, STAKE, STEEL RULE, BALL PEEN HAMMER, STRAIGHT EDGE, RIVETS, SCRIBER Procedure: The size of the given sheet metal is checked for its dimensions using a steel rule The required development of surface is being made on the white paper which is overlapped on the sheet metal. The marking is done on the sheet metal as per the development being done on the paper. Now using straight snips, unwanted materials are removed. Now fold and bend the workpiece to make the funnel shape and joint is made on the workpieces. Then using a groover, a locked grooved joint is made for about 5mm. Also, hemming is done in the bottom of the funnel. In between top face and bottom face, a butt joint is made using a solder. Finally, trimming and finishing operations are carried out. Safety Precautions:- Each cut you make exposes sharp
