Bend Radius and Angle
Calculate the bend radius and the angle from the length of the curve and the height. This calculator uses inches for measurements. You do not always know the angle or the bend radius to calculate the volume of a curved section of pipe, but the two measurements needed for this calculation are easy to get.
Bend Radius and Angle
Calculator
- enter the curve length in inches
- the height of the curve in inches
- decimal precision, the number of digits after the decimal point
Results
- the bend radius in inches
- the internal angle in radians
- in decimal degrees
- in degrees, minutes, and seconds
Formula
r = (d²/h+h)/2 a = sin-1(d/r) where r is the bend radius the angle in radians d half the length of the curve h the height of the curve r the bend radius
