The take-off for a 30-degree elbow can be calculated using the formula: Take-off = Pipe Diameter × 0.577. For example, if the pipe diameter is 4 inches, the take-off would be 4 × 0.577 = 2.308 inches. This formula helps determine the horizontal run of the pipe after the elbow joint.
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"

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.

To calculate a 45-degree elbow takeoff, you need to consider the diameter of the pipe and the flow rate. Typically, you can use the formula for an elbow fitting's pressure loss, which is based on the flow velocity and the elbow's characteristics. Additionally, you may need to refer to manufacturer data or standards that provide specific loss coefficients for a 45-degree elbow to ensure accurate pressure drop calculations in your system.
