Hydraulic resistance to movement of a drill suspended by a cable in a bore-hole in travels
Equations are given for calculation of the hydraulic resistance force to movement of a drill suspended by cable and the speed of its movement as a function of the dimension and mass of the drill and properties of the hole liquid. The most significant factor influencing the hydraulic resistance durin...
