I'm confused by your use of the term, center to center. I'm guessing you mean from the face of the fitting where the pipe threads in. You can usually screw in about 1/2 inch of pipe into a female fitting, so you would need 10 inches to end up with 9 in between. You can screw this together without a union in between? You can only put pipe together in one direction unless you use a union.
The longest distance in a circle is its diameter.
Diameter is the distance across a circle. The circumference of a circle is the distance around the outside of the circle.
The perimeter or circumference is the distance around a circle whereas the diameter is the distance across a circle through its centre.
The diameter.
The longest distance across a circle is its diameter and the shortest distance is a minor chord
This distance is called the diameter.
you measure your distance from where you want your pipework to start and finishing multiply the distance by 1.414,when you get your answer you subtract the centers of your 45 degree fittings this will give your travel between your fittings
The longest distance in a circle is its diameter.
The diameter of the Sun is approximately 1 million miles; the distance between the Earth and the Sun varies from about 91.5 million to 94.5 million miles. So the distance between is MUCH greater than the diameter.
Diameter is the distance across a circle. The circumference of a circle is the distance around the outside of the circle.
The diameter of the Sun is much larger than the distance between the Earth and the Moon. The diameter of the Sun is about 1.4 million kilometers, while the average distance between the Earth and the Moon is about 384,400 kilometers.
The circumference is the distance around. The diameter is the distance across. The radius is half the diameter, from the center to the rim.
The perimeter or circumference is the distance around a circle whereas the diameter is the distance across a circle through its centre.
The diameter.
The distance between the Equator and the Latitude i think??
Radius is the shortest distance via straight line between the center point of the circle and its perimeter. Diameter is the greatest distance via straight line from one perimeter of the circle to the opposite perimeter. Diameter = 2x Radius.
The longest distance across a circle is its diameter and the shortest distance is a minor chord
