Darcy-Weisbach Equations for Hydraulics Fluid Mechanics In fluid dynamics, the Darcy–Weisbach equation is an empirical equation that relates the head loss or pressure loss due to friction along a given length of pipe to the average velocity of the fluid flow for an incompressible fluid. The equation is named after Henry Darcy and Julius Weisbach. Darcy-Weisbach equations are used to calculate the major pressure or head loss due to friction in pipes, ducts, or tubes. Formula: h = fLvΒ²/2Dg Where: h - is the head loss f - is the friction factor L - is the pipe length D - is the pipe diameter v - is the flow velocity g - is the acceleration of gravity Thanks for your support, and do visit nitrio.com for more apps for your iOS devices.

Torricelli's Theorem Calculator Based on Torricelli's Law, also known as Torricelli's Theorem, this calculator is a tool in fluid dynamics that relates the speed of fluid flowing out of an opening to the height of the fluid above the opening. Features: β€’ Input parameters such as Tank Height, Tank Radius, Spigot Height, and Spigot Radius. β€’ Simulate water flowing out from the tank in 3D. β€’ Simulate the volume of water remaining over time. β€’ Simulate water pressure over time. β€’ Simulate water speed at the spigot over time. β€’ Simulate water distance over time. β€’ Simulate the farthest water height remaining over time. β€’ Simulate the time needed for the water to flow out until reaching the spigot height. β€’ Works seamlessly on both iPhone and iPad. β€’ Lightweight, compact app optimized for everyday use. β€’ Ad-free and built with privacy in mind. Torricelli's Theorem states that if a tank contains liquid and is open to the atmosphere at its top, and there is an orifice in the tank at a height h below the top of the liquid, then the speed of outflow from the orifice is √2gh, provided the liquid obeys Bernoulli's equation and the top of the liquid can be regarded as motionless. Torricelli's Theorem Formula: v = √2 * g * h where: v : Fluid Speed at the Orifice, in meters per second (m/s) h : Height of the Orifice from the Top, in meters (m) g : The acceleration due to gravity, 9.80665 m/sΒ² Thanks for your support, and do visit nitrio.com for more apps for your iOS devices.
