I'm a physics noob with a question that will probably stump nobody in this forum, but which Google can't seem to answer straightforwardly for me.
Here it is: I want to build three hot tubs which will all be connected via two 2-inch tubes at the bottom. The tubs will all be the same height, and situated level with one another. Two will have 150 gallons of water, one will have 300 gallons of water.
Will the additional volume in the 300 gallon tank equate to more pressure at the 2-inch tubes, such that the water level might not be the same across all three tanks? Put another way, if I sit in one of the 150 gallon tanks, will the water I displace move to the adjacent 300 gallon tank?
