Pressure requirements at a fire hydrant

I am designing a fire hydrant connecting to a point of water source which is about 2000 feet away, which needs a proper pipe size (8”, 10” or 12”) based on the pressure loss and residual pressure at the fire hydrant.

Now the questions are:

How to determine if the standpipe system is an automatic or manual? Wet/dry system?

What is the required pressure at the fire hydrant for a maul or automatic system?
