To calculate elbow take off in aerodynamics, you typically measure the angle of the elbow from the airfoil and its distance from the leading edge of the wing. This information is used to determine the change in lift and drag forces at different angles of attack. Elbow take off is important for understanding the aerodynamic performance of aircraft components.
A slang name for the skin on the elbow is "elbow grease."
The take-off velocity of an airplane is typically calculated using a variety of factors such as aircraft weight, air density, runway length, and engine thrust. Engineers use performance charts and computer simulations to determine the required take-off velocity for a specific aircraft and operating conditions. Pilots then reference these calculated values to ensure a safe and successful take-off.
The fingers are distal to the elbow, meaning they are farther away from the body compared to the elbow.
The elbow is a hinge joint.
Elbow joint.
how to calculate the elbow radius or elbow length
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.

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.
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 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.

In the area of industrial pipe fittings: Long radius 90 deg elbow has a take off dimension of one and one half times the nominal diameter of the pipe. Ex-4 inch pipe has an actual diameter of 4.5, for the elbow the take off dimension would be 4"*1.5=6". The short radius elbow take off dimension is the same as the nominal size, 4". To add to the point, a short radius elbow can be used typically where space is a constraint. Hence fluid flow is also restricted in this case unlike in case using of Long Elbow.
