What is the take out for a 4 inch 90 degree elbow?

How big is one inch in diameter?
A US 25 cent piece, a quarter, is close to one inch in diameter; it is just short. Its diameter is just about 15/16 of an inch. The diameter of a circle is the length all the way across the face of the circle going straight through the center. So a quarter gives you a good estimate of a circle with one inch diameter. Just imagine a circle very slightly bigger across.If you take an ordinary lead pencil and trace a circle using a US quarter as your template, you'll probably come even closer to a one inch diameter circle. Test it out with a ruler handy so you can get a better sense of it.
