Hydraulic Diameter of Circular Tube with Circular Tube on the InsideThe flow is in the volume between the inside and outside pipe.Based on equation (1) the hydraulic diameter of a circular duct or tube with an inside duct or tube can be expressed as...
For a circular piston, the area of its base is (3.2)A=πr2 where r = radius of cylinder. Because the diameter of the cylinder, d, is twice the radius, Eq. (3.2) can be rewritten: (3.3)A=πd24 or (3.4)A=0.7854d2 In these equations, the internal radius or diameter of the cy...
It is acting on the area on the bottom of the piston, A. The force, F, is transmitted to the right by the piston and the connected rod. For a circular piston, the area of its base is (3.2)A=πr2 where r = radius of cylinder. Because the diameter of the cylinder, d, is ...
