The formula for a long radius 90-degree elbow in piping is typically described by its radius and angle. The radius (R) is measured from the centerline of the pipe to the centerline of the elbow, with long radius elbows typically having a radius that is 1.5 times the nominal pipe diameter (1.5D). This design minimizes pressure loss and turbulence in fluid flow compared to short radius elbows.
Yes, to calculate the length of pipe needed for a 90-degree elbow, you can use the formula: Length = (Distance from the center of the elbow to the center of the next fitting) - (Radius of the elbow). The radius is typically specified by the elbow type (e.g., short or long radius). Additionally, consider any allowances for fitting tolerances when cutting the pipe.

Radius=C=1.5*NPS nps=nominal pipe size
The formula for a long radius elbow, commonly used in piping systems, is based on the radius of curvature. The long radius elbow typically has a radius that is 1.5 times the nominal pipe diameter (D), expressed as: [ R = 1.5D ] where ( R ) is the radius of the elbow. This design helps to minimize pressure loss and turbulence in fluid flow compared to short radius elbows.
Formula for calculating center to end distance of such elbows is as follows: For 90° Long Radius elbows, center to end dimension given in dimension tables of ASME B16.9 is same as radius of elbow. This is because Tan (90/2) i.e. Tan 45 is 1. Normally custom elbow angles from 45 degree to 90 are cut from 90 degree standard elbow. If that's what you were asking about...
If radius is short it is 1 times pipe diameter. If it is a long radius it is 1.5 times nominal pipe diameter.

The radius of a circle is half of its diameter. If you are referring to a circle with a diameter of 90 meters, then the radius would be 45 meters. If 90 meters is already specified as the radius, then the radius is simply 90 meters.
If you mean a circle, use the formula for the area of a circle: A = pi x r2.
The formula for the surface area of an elbow (or 90° angle) is (pi^2 * (radius2^2 - radius1^2) ) / 4. Where pi = 3.14159, radius 2 = the radius from the center to the outside, and radius 1 = the radius from the center to the inside.
The primary difference between a long radius (LR) and a short radius (SR) 90-degree elbow lies in the curvature and the radius of the bend. A long radius elbow has a center-to-end distance that is greater, typically 1.5 times the pipe diameter, allowing for a smoother flow of fluid and reduced turbulence. In contrast, a short radius elbow has a tighter bend, with a center-to-end distance that is equal to the pipe diameter, which can lead to increased pressure drop and turbulence in the flow. These characteristics make long radius elbows more suitable for applications where minimizing flow resistance is critical.
If your elbow is a short radius it is 1 times your nominal pipe diameter. If it is a long radius it is 1 1/2 times your nominal pipe diameter.show me the exact pattern of long radius
Short Radius 90 degree elbows are the same as pipe size.... Long Radius 90's are pipe size times 1.5.... so a 6" (SR) elbow is 6"... a 6" (LR) elbow would be 9"
