Properties of Fluid: Pressure and Temperature! 1. Pressure: The pressure is a force applied per unit area and is measured in units N/m2 or pascal. The absolute pressure of a gas is the result of a large number of the molecules forming the gas striking the walls of the vessel. The force per unit area is called the specific pressure [...]

The Flow Nozzle 5. Free Jets. Flow Measuring Devices: Types of Flow Meters and their Applications Flow Measuring Device # 1. The Venturimeter: A Venturimeter is a [...]
A mouth piece is a short pipe fitted externally or internally to an orifice. The length of the mouth piece is 2 to 3 times the diameter of the orifice to which it is fitted. Mouth pieces may be classified based on their position, their shape and the manner in which the mouth piece discharges. Mouth pieces may be external [...]
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 [...]
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 [...]
