12.Research the reason of influence the mediμm radius horizontal well drilling speed in the shallow layer影响浅层中半径水平井钻井速度的原因探讨 13.The maximum shearing stress to which the material is subjected has a value equal to the radius of the circle.材料承受的最大应力数值等于圆的半径。
1. A full pipe There's nothing easier than finding the hydraulic radius of a pipe completely filled with liquid. All you have to do is use the formulas for the area and perimeter of a circle! R = A / P = πr² / 2πr = r/2 As you can see, the hydraulic radius of a full...

On the basis of analyzing the relationship between pressure before the nozzle and nozzle area,radius of throw,a new type of variable-rate sprinkler was developed by using activity pieces and non-circle nozzle device on an impact sprinkler.The structure and working principles were presented.Experiment...
Further efficiency is achieved through avoidance of horizontal forces on the well-head linkage by fashioning the horseheads to have the face farthest from the center of rotation of the fulcrum beam be a convex portion of a circle circumference whose radius is the distance to the center of ...
Groove between knife projections is made toroidal, with radius of circle forming the torus, equal to height of projection, and center of torus is located in plane of sealing edges of knife projections. Guaranteed ring clearance to pass working medium set between outer surface of small step of ...
The improvement of the present invention is that, in combination, the blades have a profile of an arc of a circle, and the portions of the stator ring which define the injector gaps each have a plane terminal face inclined at substantially 45° to the corresponding radius of the ...
σave=Pe,clpr2πa2. The contact circle radius (r), the contact depth (δ), and the average contact stress can be expressed respectively as r=3Pe,clpr2R4E⁎1/3 δ=3Pe,clpr2R4E⁎2/31R σave=23π6Pe,clpr2E⁎2R21/3. The elastic deformation of proppants is generally assumed for...
