The original post is below.  I have a weak background in physics, so could someone help me please?  I know there is someone out there wanting to show off their mad skills.  I know that trying to apply real world physics to D&D is dangerous, but this involves set forces so it shouldn't be a problem.Assume you have a Decantur of Endless Water, set at the geyser setting.• “Stream” pours out 1 gallon per round.• “Fountain” produces a 5-foot-long stream at 5 gallons per round.• “Geyser” produces a 20-foot-long, 1-foot-wide stream at 30 gallons per round.Before you turn the decantur on, you mount it in a boat of varying size.  First a two man canoe, then a 15 ft by 15 raft with 1 ft thick logs, then a 10 ft by 10 ft raft with 1 ft thick logs.  Assume the logs are oak if that helps with density calculations.The decantur opening plays a large role in determining the force of the blast, so if the formula is easy to calculate, assume 1 inch, 1.5 inches, and 2 inches as the opening size.  Perhaps you might come up with a more reasonable size; I don't have a decantur in front of me right now.When mounted underneath a boat, how much force does the decantur output?  Assuming the rafts had 1200 lbs of equipment and adventurers in it, how fast would it go in real speed and D&D ft/round. What would be its maneuverability rating, per the DMG?  If the canoe had 400 lbs of gear/people, how fast would it go?  How many parts to a multi-part series of questions is too many?For bonus points, calculate the velocity of an unladen swallow (African & European), a swallow with a coconut, and a swallow with a decantur on geyser mode as they move away from the ground.I really would like the answers to the decantur questions because I have always been curious and I am designing an adventure.  If calculating is too much, please give a formula and I'll plug in the numbers myself, although I would like the formula anyway.Thank you all for your time and busy calculations,</blockquote>
