It is the radius of bend of the elbow with reference to a point,the point is determined by the intersection of two lines from the elbows socket end (which makes the shape of one quater of a circle). The bend ie; 1.5d,3d,5d,10d is determined from that point of intersection as a multiple of elbows diameter.
4 inch 5d bend 45degree elbow center how much
3d is visual, 4d is visual and interactive such a a 3d rollercoaster ride where the chair tilts, i'm guessing 5 and 6d will be full immersion with surround screen so it is all around you with holographic characters that look like they are standing next to you, maybe with temperature fluctuations and the long anticipated smell-o-vision!!

There is no difference. Different suppliers and contractor describe the same situation with 3R or 3D. Here is how to think about it. A piping segment is formed or bent at a radius. The radius is measured at the centerline of the bend. The radius of the bend centerline is 3 times the nominal diameter of the piping segment being bent. 3R means the bend radii is three times the nominal pipe diameter. 3D means three times the nominal pipe diameter is the bend radii of the piping segment. Caution don't begin to convert 3R to 1.5D. Not applicable with this terminology. Standard long ells can be purchased with 3R bends, being 10 inch pipe ells have a bend radii of 30 inches.
a(c - 5d) - 5b(c + 5d)
5d bend
5d + 2(3d) 5d + 6d 11d
4e + 3d + 5e - 5d = 9e - 2d
5d+3d = 15 8d = 15 d = 15/8 = 1.875

we do not have any clue of 5D if we cannot go into 4D. 3D going into 4D is impossible. finding out 5D is impossible.
8d = 5d+18 8d-5d = 18 3d = 18 d = 6

The RADIUS of a 5D pipe bend is actually what is 5 times the nominal diameter. So if you had a 10" diameter pipe, the radius of the centerline of the bend would be 50 inches.
2(3d+7)=5+5d. 6d+14=5+5d 6d+9=5d 9=-1d d=-9 I think that's correct. If it is, ur welcome.
I assume those are diopters. When combining two lenses, you can simply add their power. More precisely, add algebraically, that is, taking their signs into account.
You can virtually a 3D pipe bend by using a bend machine. This is can create a lot of different single and multiple bends making the pieces form into shapes.
