Hydraulic head is one of the key parameters describing the mechanical energy state of a hydraulic system. It represents the mechanical energy per unit weight of the fluid in the system. Hydraulic head is defined as h = hp + hz, where h is the hydraulic head, hp is the pressure head, an...

As an explanation, it was inferred that the CCD approach is based on linear fracture mechanics, which is valid for the smaller fastener heads (i.e. high bearing pressure). High pressure at the bearing head leads to a complex mixed mode fracture. In such extreme conditions, the crack length...
a bigger aperture ratio will result in a smaller pressure difference.Based on the theory of fluid mechanics,this paper deduces a calculation formula of the pressure difference,which is verified by the site monitoring data and modified by the results of discrete element method.The research ...
Forum:Mechanics B Under pressure -- flow rate through multiple holes in a pipe I am looking at air system that is under a constant pressure of 350 mbar into a pipe that has 40 - 2 mm round holes. Is there a formula that I can use to calculate the total volume of air nm3/hr that...

The pressure of a liquid due to its fluid head is also dependent on the density of the liquid. If we let A equal any cross-sectional area of a liquid column and h equal the depth of the column, the volume becomes Ah. Using the equation D = W/V, the weight of the liquid above ...
I then calculated the reynolds number of the pipe by the formula ((denistyxVxD)/(dynamic viscosity)) giving me a reynolds number of 106143.75. Then at k/D .004 and reynolds 1E5 on the moody diagram to find a friction factor,f, of .03 which i put into the formula headloss due ...
