hi need ur help 4 dis . What data is needed to fabricate a 16 inch pipe elbow?
.625'' x pipe diameter
233
15.875 x pipe size=
The take off formula of a 45 degree elbow pipe, will depend on what the pipe is on. Sometimes a 45 degree pipe will need a 90 degree right angle turn to come off.
5/8 x pipe size
Radius=C=1.5*NPS nps=nominal pipe size
(Pi*(Center of elbow - od/2)^2-(pi*(Center of elbow+od/2)^2)รท4)รท100000=0.221 Square Meter
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 easiest way is to find the centerline length and multiply that by the linear weight of the pipe size being used. Alternatively, this formula should give the weight of an elbow in pounds: w=0.071*pi^2*R*(ro^2-ri^2) Where: w= weight of elbow (lb) R=curve radius of elbow (in) ro=outside radius of pipe (in) ri=inside radius of pipe (in)

The formula for volume of a liquid in the pipe is V=(pi/4)D2 (L)
