NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
Furthermore, in astronomy and geophysics, a nominal radius of earth is sometimes employed as a unit of measurement. 6,371 kilometres is commonly used as a global average value. The radius of curvature is another approach to define and measure the Earth radius, and some definitions produce resul...
Cstd: r/d of a standard elbow; Cstd is set equal to 1.5; ρf: fluid density; μf: fluid viscosity; dp: particle diameter; r: radius of curvature of the elbow. This equation accounts for the elbow radius curvature effect in different carrier fluids and sand particle size. Note that thi...
ie R = 1.5D. A short-radius elbow means that its radius of curvature is equal to the outer diameter of the tube, ie R = 1.0D. (D is the diameter of the elbow, and R is the radius of curvature. D can also be expressed in terms of folds.) If there are 17 levels depending on...
tmClass This gear for the transmission is characterized in that the tooth surfaces consist of free curved surfaces where the minimumradiusof curvature in the vicinity of engagementpitchpoints is maximized, and that the tooth base surfaces consist of free curved surfaces where the minimumradiusof curv...
A short radius elbow means that its radius of curvature is equal to the outer diameter of the tube, ie R = D. Where D is the diameter of the elbow and R is the radius of curvature.
A short radius elbow means that its radius of curvature is equal to the outer diameter of the tube, ie R = D. Where D is the diameter of the elbow and R is the radius of curvature. Normal use of the length of the radius Sometimes to reduce the loss of resistance or elbow wear, ...
The long radius elbow refers to the outer diameter of the tube whose radius of curvature is equal to 1.5 times, that is, R = 1.5D.

An ellipsoid corneal modeler includes an ellipsoid fitter which utilizes two radii of curvature, asphericity (Q), and a surface rotation about the pupil center (roation of θ), yielding the equation: 1 x 2 R x + y 2 R y + z z ( 2 R x R y ( 1 + Q ) R x ...
