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 … Read more
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 … Read more
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 … Read more
