In general, all the materials used by the engineers, may be classified, on the basis of their physical properties, into the following four types: 1) Elastic materials : When a material regains its original position, on the removal of the …
The ratio of velocity of fluid, in an undisturbed stream (Vl), to the velocity of sound wave (Vs) is known as Mach Number. It gives us an important information about the type of flow. In general, the flow of a …
The important force present in a moving liquid are as follows: a) Inertia force : It is the product of mass and acceleration of the moving liquid. b) Viscous force : It is the product of shear stress due to viscosity …
a) Reynold’s number: It is the ratio of the inertia force to the viscous force. b) Froude’s number: It is the ratio of the inertia force to the gravity force. c) Weber’s number: It is the ratio of the inertia …
A notch may be defined as an opening provided in the side of a tank or vessel such that the liquid surface in the tank is below the top edge of the opening. It is generally made of a metallic …
The following are the hydraulic coefficient: 1. Coefficient of contraction (Cc)It is defined as the ratio of area of jet at vena contracta (Ac) to the area of the orifice (A) . 2) Coefficient of Velocity (Cv)It is deifined as …
WHAT DO I DO ? When I used to be in the final year of my engineering, I used to think what actually we have to do after joining the job. If you are a fresher or engineering student, you may …
The equilibrium of floating bodies is of the following three types: 1) Stable Equilibrium: If the body floating in a liquid returns back to its original position, when given a small angular displacement, then the body is said to be …
The following are the three types of energies or head of the flowing liquids: 1) Potential energy or potential headIt is due to the position above some suitable datum line. It is denoted by z. 2) Kinetic energy or kinetic …
