The drag force due to fluid flow past an immersed object is the air resistance or water resistance due to the fluid. The Reynolds number helps to …
Continue ReadingMeasurement of air velocity is a common use of pitot tubes, but they can be used to measure the velocity of other fluids as well. In order to …
Continue ReadingWe found the total kinetic energy of flow using the average velocity of flow. This is true because we don’t consider the viscous effects. But in real …
Continue ReadingThe major component of loss in energy of fluids flowing through different conduits is attributed to frictional losses. But sudden changes in flow …
Continue ReadingWhen constructed, the Venice tide barriers will be the biggest dam construction in the world. A product of extraordinary civil engineering skills, the …
Continue ReadingThe Reynolds number is used to calculate the entrance length needed to reach fully developed flow for turbulent flow or for laminar flow in a pipe. At …
Continue ReadingBiochemical oxygen demand (BOD) is a measure of organic pollutants, one of the causes of water pollution. In the organic carbon cycle, organic …
Continue ReadingFrictional head loss (or pressure drop) in pipe flow is related to the friction factor and flow velocity by the Darcy Weisbach equation. Reynolds …
Continue ReadingA hydraulic jump occurs in open channel flow where supercritical flow (Froude number > 1) is taking place on a slope that cannot maintain …
Continue ReadingPipe flow may be either laminar flow or turbulent flow. Laminar flow is characterized by low flow velocity and high viscosity. Turbulent flow is …
Continue ReadingNothing is ideal in this world so how can be fluid flow so simple. The model of ideal fluid flow is good for understanding and solving the fluid flow …
Continue ReadingMost of us must have come across river dams at least once in our life. But how often do we see or hear about dams across seas? The Netherlands North …
