Velocity-Area Flowmetering Flow rate or discharge in an open conduit, channel or river can be calculated with the velocity-area principle.Underground Pipes - Earth Pressure Pressure acting on underground pipes due to weight of soil and transport. Pressure Converting head (ft or m) to pressure (psi or bar, kg/cm 2) and vice versa. Pressure Units - Online Converter Convert between pressure units like Pa, bar, atmosphere, pound square feet, psi and more.Pressure Gradient Diagrams Static pressure graphical presentation throughout a fluid flow system.Pressure Introduction to pressure - online pressure units converter.Hydrostatic Force acting on Submerged Surface Calculate the thrust force acting on a submerged surface.Pressure and Cylinder Size Calculate hydraulic cylinder force. Pascal's Law Pascal's law and the hydraulic force acting in fluids. Buoyancy Buoyancy is the resultant force acting on a submerged body.Archimedes' Law Forces acting on bodies submerged in fluids.Involving velocity, pressure, density and temperature as functions of space and time. Fluid Mechanics The study of fluids - liquids and gases. Ocean pressure varies with depth and position (latitude) on earth. The pressure acting in water at 3 ft can be calculated as The density of water at 32 oF is 1.940 slugs/ft 3. = 9810 Pa Example - Pressure acting in water at depth 3 ft The pressure acting in water at 1 m can be calculated as The density of water at 4 oC is 1000 kg/m 3. Hydrostatic pressure in a water column - or depth ( density of water 1000 kg/m 3): Height of Water ColumnĮxample - Pressure acting in water at depth 1 m H = height of fluid column - or depth in the fluid where pressure is measured (m, ft) Ρ = density of liquid (kg/m 3, slugs/ft 3) P = pressure in liquid (N/m 2, Pa, lb f/ft 2, psf) Hydrostatic pressure in a liquid can be calculated as
