An orifice may be defined as an opening provided in the side or bottom of a tank, for the purpose of discharging the liquid contained in the tank. It should be noted that the opening will be considered as an orifice only when the liquid surface in the tank is above the upper edge of the opening. Orifices may be [...]
Learn about the effects of temperature on viscosity of liquids. In this article we will discuss about variation of viscosity of fluid. Also learn about:- 1. Concept of Dynamic Viscosity as a Modulus 2. Determination of Viscosity. Variation of Viscosity with Temperature: The viscosity of a fluid is due to two contributing factors, namely the cohesion between the fluid molecules [...]
In this article we will discuss about:- 1. Meaning of Fluid 2. Perfect and Actual Fluid 3. Units of Fluid Measurement 4. Properties. Meaning of Fluid: A fluid is a substance which offers no resistance to shear deformation and will continue to deform when subjected to shear stresses. A fluid has no definite shape, and it takes the shape of [...]

Compilation of notes on buoyancy and floatation for engineering students. Note # 1. Meaning of Buoyancy: Consider a body immersed in a liquid. Consider an elemental vertical cylinder of the body of height y and sectional area da. Let the intensity of pressure on the top end of the cylinder be p. The intensity of pressure on the bottom of [...]
Relative Equilibrium of Fluids: Examples, Problems, and Formulas! Liquid Mass Subjected to Uniform Linear Horizontal Acceleration: Fig. 5.1 shows an open tank containing a liquid. When the tank moves horizontally with uniform acceleration, the surface of the liquid which was horizontal earlier will now be at some inclination θ with the horizontal. The level of liquid falls at the front [...]
Fundamentals of Equations of Fluid Flow: Bernoulli's Theorem and it’s Application! Bernoulli's Theorem: This theorem is a form of the well-known principle of conservation of energy. The theorem is stated as follows: In a steady continuous flow of a frictionless incompressible fluid, the sum of the potential head, the pressure head and the kinetic head is the same at all [...]
Kinematics of Fluid Flow: Notes, Methods, Problems and Solutions! This article will help you to get the probable answers for the questions related to Kinematics of Fluid Flow. Kinematics of fluid flow deals with the motion of fluid particles without considering the agency producing the motion. This deals with the geometry of motion of fluid particles. This also deals with [...]
