Use a compass to accurately draw the hole. Bore a hole thru the sheet metal big enough to allow pointed tin snips to start cutting. Follow the line with tin snips until the hole is completed.
The recommended diameter for a 4 inch duct pipe for proper ventilation in a residential setting is typically around 4 inches.
The recommended diameter for a duct in a ventilation system that requires optimal airflow is typically around 8 inches. However, a 7-inch duct can still provide sufficient airflow depending on the specific requirements of the system.
If the snake is six inches long and the hole is two inches in diameter, then yes. Otherwise, no.
To calculate the square meters of a duct you must add the total length of the straight duct work plus the loss of length from the elbows. A standard elbows measurement is 15 feet for each elbow with a 4 inch diameter or 20 feet for an elbow with a 6 inch diameter.
The recommended size for an oval duct to be used in a ventilation system with a 4-inch diameter is typically 3 inches by 6 inches.
7/8 diameter drill or .875
yes u can if u are good with duct work put a down draft furnace in a basement and pipe it up one floor well not recommended it will work i did this to help a lady get threw winter who had low funds and it has worked quite well u need to build a custom box for the furnace to sit on to make this work and pipe directly from box and use smallest duct work u can i.e mobile home duct work or 4 to 6 inch What you did is still a downdraft furnace
To accommodate a 3/8 bolt, drill a hole that is 3/8 inch in diameter.
Use something like Duct Tape to make a backing and fill the hole as much as possible with this. The use a putty knife to get the stucco material in the hole and to cover it, going up and down and side to side. You can then immediately paint over the patched spot, no need to wait on it to dry!
The standard 10 screw hole size for mounting hardware is 3/16 inch in diameter.
Concrete is reckoned by the cubic yard. But the hole mentioned only has two dimensions given - so I have to make an assumption, that it is an 84 inch deep round hole whose diameter is 24 inches. If this is the case, I work out the volume of the hole like this: volume of cylinder is pi times diameter times diameter times depth divided by four. 24 inch = 0.67 yard 84 inch = 2.33 yard So the volume is 3.14 X 0.67 X 0.67 X 2.33 / 4 cubic yards = 0.815 cubic yards. /BrianW
An inch is a unit of measurement. It has no diameter.
