From the Gauckler-Manning formula for open channel flow one can calculate the head losses from friction of the pond bottom (h friction) and flow around each bend (h bend) (36) (37) where n 0 is a roughness factor also known as the Gauckler-Manning coefficient, r is the channel hydraulic radius, α 7 is the kinetic loss coefficient, and g is the acceleration of gravity.

A Method of Quick and Safe Coal Uncovering by Hydraulic ...

Hydraulic punching prevents coal and gas outburst by reducing the gas content in a coal seam and altering the stress state of the coal seam. This method is applicable to relatively hard coal. If it is applied to a soft coal seam, the proppant tends to be embedded in coal and then loses its supporting function.

This grade is the height to which a column of water would rise in a Pitot tube (an apparatus similar to a piezometer, but also accounting for fluid velocity). When plotted in profile, this parameter is often referred to as the energy grade line, or EGL. For a lake or reservoir in which the velocity is essentially zero, the EGL is equal to the HGL.

Q is the steady state flow rate of water into the well hole [cm^3][sec^-1], H is the depth of water in the hole [cm], a is the radius of the auger hole [cm] and C is a dimensionless shape ,parameter, that depends mainly on the H/a ratio and to a lesser extent on the K(0)/phi ratio (see Reynolds et al., 1985).

Abstract. A simple ,parameter,, called the Aneurysm number ( An) which is defined as the ratio of transport to vortex time scales, has been shown to classify the flow mode in simplified aneurysm geometries. Our objective is to test the hypothesis that An can classify the flow in …
