Calculating the Bollard Pull of a Tug Boat?
1) First up draw BODY PLAN for your tug boat with reasonable number of stations.. 2) Find the sectional areas (of each station) from the body plan till the required draft... 3) Then using simpson's rule,simpsonize the areas and find the volume... 4) Then find the summation of volume.. this gives the volume of displacement.. 5) We can hence find bollard pull using the relation Bollard pull = ((Displacement * 60)/1,00,000)+ 40

What mathematical formula do architectural engineers use in calculating the bollard pull of a tug boat?
Engineers use almost all mathematical formulas that exist, since engineering covers the entire range of science. Normally we use a simple formula if tug has amain engines and standard 4:1 gear box : we use formula of 1/ 10 if you bhp is 900 , you get Normal 9 bollard pull how ever if you have Kort nozzles & K type propeller you can multiply by 1.3 henf 9 x 1.3 = 11.7 approx 12 you have to do Bolard pul test wiht Steel wire rope as it has no Give and use a standard length of 120 meters sea condition has ot be "CALM " or Still normally one hour after high tide angle of rope has to not over 2 - 5 degrees over 120 meter never do Bollard pull test with Nylon ropes or length below 120 meters the test is then invalid you can get very high bollard pul if you increase Reduction gear by say 16 : 1 and use large Pitch and Diameter propllers wiht slow speed engines max 100 rpm - 120 rpm call me if you need advice
What happened if torn off the pump in a pool above ground?
The pump acts as the suction to pull the water into the filter and return it to the pool's jets. What item was torn off? You would have to close the valves on your returns so the pool's water does not come out through the broken part. Can you post pics or explain more? Good luck!
