From that, we can estimate the radius (the inside radius) and then knowing the Outer Diameter of the bend, we can estimate the CLR (Center-Line-Radius).Ī radius of a circle is the length of a line from the center of a circle to its perimeter. What we need to do is estimate the circle that the inside curve of the bend makes. So, with a few principles, we can get a close approximation of the bend radius even from the photograph. Pictured here, is our result and the radius of 9″ is quite different! The customer was not careful to measure the true arc of the bend, and thus, estimated a much larger circle. Your gut feeling is that if you replace this with a 24″ radius bend, your customer will not be happy about the result. They can’t ship you the old bend because they are still using it. Imagine if you got a picture like this in your email and your customer said, “make us one just like this.” On top of that, they insist that this is a bend on a 24″ radius.

R px = resulting force due to pressure in x-direction (N) The resulting force in x-direction can be expressed as The pressure "acting" on the end surfaces of the bend creates resulting forces in x- and y-directions. Note - if β is 90 othe resulting forces in x- and y-directions are the same. R = resulting force on the bend (N) Example - Resulting force on a bend due to mass flow and flow velocity The resulting force on the bend due to force in x- and y-direction can be expressed as: The resulting force in y-direction due to mass flow and flow velocity can be expressed as:
