The following are the important expressions used in orifices and mouthpieces including discharge through large rectangular orifice, discharge through wholly submerged orifice, and more: (a) Discharge through a large rectangular orifice, where Cd = Coefficient of discharge, b = Breadth of the orifice, H1 = Height of the liquid above the top of the orifice, and…

Internal combustion engines can be classified into a large number of types based on several criteria. The classification of IC engines is given below: 1.      Based on the fuel used ·         Diesel Engine ·         Petrol Engine (or Gasoline Engine) 2.      Based on the type of cycle ·         Otto Cycle Engine ·         Diesel Cycle Engine ·         Dual Cycle Engine 3.      Based on the number of strokes…

Non-ferrous metals and alloys – We have already discussed that the non-ferrous metals are those which contain a metal other than iron as their chief constituent. The various non-ferrous metals used in engineering practice are aluminum, copper, lead, tin, zinc, nickel etc. and their alloys. These non-ferrous metals and their alloys are discussed, in brief, as…

It is a step by step value addition process of converting one form of the material into another form, to increase the utility of the product for the user. Production system: It is an organized process of converting the raw material into final product with the help of the feedback loop. Productivity: It is a…

The following are the important expressions used in notches and weirs.  (a) Discharge over a rectangular notch or weir, where b = Width of notch or weir, and H = Height of liquid above the sill of the notch. (b) Discharge over a triangular notch or weir, For a right angled V-notch, Theeta = 90°. (c) Discharge over a trapezoidal…

Often materials are subject to external force when they are used. Mechanical Engineers calculate those forces and material scientists how materials deform or break as a function of force, time, temperature, and other conditions. Materials scientists learn about these mechanical properties by testing materials. Some of the important mechanical properties of a metals are Brittleness, Creep, Ductility,…

In casting process, first few castings will be inspected dimensionally and the pattern is qualified afterwards, only few random inspection will be done. Every casting must be inspected for finding out the defects in casting process. Different methods of inspection for finding out defects in casting process are discussed below 1.      Visual Inspection 2.      Hydrostatic Pressure Test 3.      Magnetic Particle…

Mechanical properties consist of tensile strength, toughness, malleability, hardness, Ductility, stiffness, brittle ness, Elasticity, plasticity etc. Tensile strength Tensile strength is the ability of the material to withstand the tensile loads without breaking. Strength: Strength is the ability of a material to attack the applied forces without fracturing. Toughness: Toughness is the ability of the…

Kinematics is defined as the geometry of the motion. Fluid kinematics defines the motion of the fluids and its significance without taking into account of the nature of forces that cause motion. Kinematics is divided into three main features: Improvement of methods and tools for recitation and identifying the motion of fluids. Determination of the conditions…

A fastener is a hardware device that are used for creating non-permanent joints.Fasteners can be used to close a container of a box or an envelope, or they may involve keeping together the sides of an opening of flexible material, attaching a lid to a container, etc. Other alternative methods of joining processes for joining…
