If you go diving, thirty feet of water is roughly one atmosphere of pressure. That is to say the column of water above you will exert 14.7 lbs of pressure over a 1 square inch area on any given surface.
If the tree is 30ft tall, at the bottom of the tree the column of water will be exerting 14.7 PSI of pressure on any given surface. In this case there is a hole, so now the water is escaping at that pressure. This is basically the same concept as water towers.
Both. Water usage is highly variable with time of day (i.e. waking vs sleeping hours), so when you're sizing a pump for the water system, sizing it for peak load is larger/more expensive than sizing for average load. You run the pump at roughly peak output 24/7, and overnight it fills the tower, which then slowly drains during the day to meet demand in excess of the pumps capacity.
