RABUBI Posted June 20, 2007 Posted June 20, 2007 A question, Is there a formula to calculate average watts on a climb if you have the following. Ave speedEnergy expenditureGradient %Total Distancetotal Time Any of the Boffins out there know how to do this? Maybe someone doing highschool science?

ewep Posted June 20, 2007 Posted June 20, 2007 OK, here goes: x(squared) * y. Then deduct C after multiplying that with the sum of A+B. Remember to divide Z into the result. If you then find a good answer. let me know, 'cause I have NO clue what I just said!!!!

pastapouch Posted June 20, 2007 Posted June 20, 2007 Don't think school science covered that detail. I remember something about calculating the power it would take to lift an object a specific height. The formula was something with weight , the time it took and the height. Or may I'm missing the pot completely
ewep Posted June 20, 2007 Posted June 20, 2007 Don't think school science covered that detail. I remember something about calculating the power it would take to lift an object a specific height.

pastapouch Posted June 20, 2007 Posted June 20, 2007 ... but on the other hand ewep, I know that it take much more power to take you up a hill than me
ewep Posted June 20, 2007 Posted June 20, 2007 ... but on the other hand ewep' date=' I know that it take much more power to take you up a hill than me[/quote'] But at least I make it to the end of my MSD's (MEDIUM slow distance)!!!
RABUBI Posted June 20, 2007 Author Posted June 20, 2007 The calculator is Brittish, a bit confusing, what is the inches diameter for a normal road wheel? How many cm in one inch, Kg/Lbs, and km/miles?

MUNTU Posted June 20, 2007 Posted June 20, 2007 Try this one RABUBI: http://www.kreuzotter.de/english/espeed.htm
RABUBI Posted June 20, 2007 Author Posted June 20, 2007 OK, thanks for the replies, what I wanted to check was my ave Watts on the climb on the Kremetart first stage as per the Data from my Polar:Duration00:15:00Average Speed 22.0km/hDistance 5.6 kmGrade %5.0%Worked out to between 310=320 watts on average
TNT1 Posted June 20, 2007 Posted June 20, 2007 RABUBI, go to www.machinehead-software.co.uk you can download a good software kit from there to let you do power calculations.... Their power calc works on similar algorithms to i-bike... similar variables etc...
