1/4 inch per foot.
Probably the wrong size flange. Is the flange a toilet collar? If so the pipe is probably 4 inch.
you need to know the viscosity of the liquid - molasses or alcohol?
Wouldn't recommend it as things may back up in the drain line. 4" line is the norm ... you want to get rid of waste, not keep it around longer.
Answering this question leaves a lot of unknowns; 1) Is this in the basement, in the floor, under concrete, or, going to be. 2) Is this on a main level, above a basement (Not a crawl space!). And 10 more questions! There is some planning, but, could be trying to answer 25 different scenario's, as much supplied info. will help. For a short answer to keep it simple, the answer is, yes, you can!

To estimate the time to drain a 150,000-gallon water tower through three 6-inch pipes, we first need to calculate the flow rate of the pipes. A single 6-inch pipe can discharge approximately 1,000 gallons per minute (gpm) under ideal conditions, so three pipes would yield about 3,000 gpm. Dividing 150,000 gallons by 3,000 gpm gives a rough estimate of 50 minutes to drain the tank, assuming no other factors like friction loss or elevation changes affect the flow.
The recommended diameter for a 4 inch drain pipe in a residential plumbing system is typically 4 inches.

Depends on the pitch of the waste line?
Yes, easily.
