A rotameter, also known as a variable area flowmeter, is a device used to measure the flow rate of a fluid in a pipeline. It operates based on the principle of variable area, where the fluid flow causes a float or rotor to move within a conically shaped tube. The height of the float or […]
A Pitot tube is a widely used instrument for measuring the velocity of fluid flow, especially in aerodynamics and fluid dynamics applications. Named after Henri Pitot, who invented it in the 18th century, the Pitot tube relies on the principle of Bernoulli’s equation to determine fluid velocity by measuring the pressure difference between the dynamic […]
A Venturi meter is a flow measurement device used to determine the flow rate of fluid in a pipeline. It operates based on the principle of Bernoulli’s equation, utilizing the change in cross-sectional area to create a pressure difference that correlates with the fluid flow rate. Venturi meters are commonly used in various industries for […]
An orifice meter is a widely used device for measuring the flow rate of fluids in pipelines. It operates based on the principle of restricting the flow through an orifice, creating a pressure difference across the orifice that can be correlated with the flow rate. Here is a detailed note on orifice meters, including their […]
Energy losses
Energy losses occur in various systems and processes due to factors such as friction, turbulence, heat transfer, and inefficiencies inherent in the design or operation of a system. Reducing energy losses is a key focus in engineering and design to enhance the efficiency and sustainability of processes. Here are common types of energy losses and […]
Bernoulli’s Theorem: , pressure, and elevation along a streamline. The theorem is based on the conservation of energy for an ideal fluid flowing along a streamline with no external work or heat transfer. The general form of Bernoulli’s theorem is given by: where: – P is the pressure of the fluid. – ρ is the […]
Reynolds Number Osborne Reynolds introduced the Reynolds number (Re) in the late 19th century as a dimensionless quantity used in fluid mechanics to predict flow patterns in various fluid flow situations. This parameter helps determine whether the flow of a fluid, whether liquid or gas, will be laminar or turbulent. The Reynolds number is defined […]
