In a 2x8 floor joist spanning 12ft what is the largest diameter hole you can drill through for conduit?
1/3 the size of the joist, so approximately 2 1/4 in.
Keep the hole a min. of 2" from the top of the joist. If it's 2" exactly, put a nail guard on the top.
Don't put the hole within 6" of another hole. don't put the hole within 4" of a notch.
This of course all depends on the joist spacing 12"/16"/24"? And what the live load is anticipated? If it's a regular floor it's one thing, a monster tub is another.

The diameter of a circle is a circle's largest chord.
How do you get a power cable through a hose?
You should probably use electrical conduit approved for this purpose, and not hose - anything else is unsafe and will fail. To get the cable through the conduit: Find a styrofoam ball, ping-pong ball, or similar very lightweight ball just slightly smaller than the inside diameter of the conduit. Push the end of a piece of lightweight nylon twine (longer than your conduit) through the ball and tie it in a knot. On one end of the conduit, attach the hose of a shop-vac - and at the other end, drop in your ball. The vacuum will suck the ball and twine through the conduit. Retrieve the ball. Then use the twine to pull your line through the conduit (if small wire), or to pull a length of stronger rope or cable through before attaching it your wire.
How can I properly install electrical conduit through a wall?
To properly install electrical conduit through a wall, follow these steps: Plan the route and size of the conduit. Cut a hole in the wall where the conduit will pass through. Insert the conduit through the hole. Secure the conduit to the wall using appropriate fasteners. Seal any gaps around the conduit to prevent drafts or moisture. Connect the conduit to the electrical boxes on both ends. Test the conduit to ensure proper installation and functionality.
Can a chord of a circle also be a diameter of a circle?
Yes because the diameter of a circle is its largest chord passing through the center of the circle.
What is PVC 20mm conduit?

Best describes the diameter of a circle.?
The diameter of a circle is twice its radius or its largest chord passing through the center of the circle.
How can I run conduit through an exterior wall?
To run conduit through an exterior wall, you will need to carefully measure and mark the location where you want the conduit to pass through. Then, use a drill with a hole saw attachment to create a hole in the wall. Next, insert the conduit through the hole and secure it in place using appropriate fasteners. Finally, seal around the conduit with caulk or weatherproofing material to prevent water infiltration.
What is the name of the largest chord?
The largest chord in a circle is called the diameter. It spans the widest part of the circle, connecting two points on the circumference and passing through the center. The diameter is always twice the length of the radius of the circle.
All chords of a circle pass through the center of a circle?
Not true because only the largest chord passes through the center of a circle which is its diameter
How can I safely and effectively run conduit through a wall?
To safely and effectively run conduit through a wall, follow these steps: Turn off the power to the area where you will be working. Plan the conduit route and mark the locations for holes in the wall. Use a stud finder to locate and avoid electrical wires and pipes within the wall. Drill holes for the conduit using a drill with a hole saw attachment. Insert the conduit through the holes and secure it in place with conduit straps. Connect the conduit to the electrical boxes at each end. Seal any gaps around the conduit with caulk or foam to prevent drafts and moisture. Remember to follow all local building codes and regulations when running conduit through a wall.
