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"

1-13/16"= The tangent of half the degree X the radius of the elbow.
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.

The take-off for a 4-inch 90-degree elbow is typically calculated based on the diameter of the pipe and the angle of the bend. For a 4-inch diameter pipe, the take-off is generally around 10 to 12 inches. This measurement may vary slightly depending on the specific design and manufacturer of the elbow, so it's always best to refer to the manufacturer's specifications for precise dimensions.
The take-off for an 8-inch butt weld elbow typically refers to the length of pipe that is required to accommodate the elbow's angle and diameter when calculating pipe runs. For a standard 90-degree elbow, the take-off is generally about 8 inches plus the radius of the elbow, which is typically 10 inches for an 8-inch elbow, resulting in a total take-off of approximately 18 inches. For other angles (like 45 degrees), the take-off measurements would differ accordingly. Always consult specific piping codes or standards for precise measurements.

The take-off of a 45-degree elbow refers to the angle at which the elbow connects to a pipe, allowing fluid to change direction. It typically allows for smoother flow compared to sharper bends, reducing turbulence and pressure loss. This design is commonly used in plumbing and HVAC systems to maintain efficient fluid transport. The take-off measurement is crucial for ensuring compatibility with other piping components.

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.
