A mercury barometer is one of the classic uses of static pressure head. Such barometers are an enclosed column of mercury standing vertically with gradations on the tube. The lower end of the tube is bathed in a pool of mercury open to the ambient to measure the local atmospheric pressure. The reading of a mercury barometer (in mm of Hg, for example) can be converted into an absolute pressure using the above equations.

Webb17 dec. 2011 · Hv, or velocity head, is the kinetic energy of a mass of water moving at some velocity V. It is equivalent to the distance that water would have to fall in order to reach that velocity. It can be calculated by determining the velocity in the suction piping from a velocity table and substituting that value for V in the equation "h = V 2 /2g" (where …

Water moves through a groundwater system because it is acted upon by forces. There are two forces that drive flow: 1) a pressure gradient and 2) the force of gravity. If the density of the groundwater is constant, the sum of these forces acting on a unit weight of water can be conveniently expressed as the gradient of ...

Webbchezy’s constant (C) is dimensionless, it can be determined by different formulas. Here we see how it will be determined through the bazin formula, C = 157.6 1.81+ K √m C = 157.6 1.81 + K m. Here K= basin constant. m= hydraulic mean depth/ radius. here K depends on the roughness of the channel surface.
