Horsepower Calculator

A member of another forum posted a horsepower worksheet in a horsepower discussion on another forum. I converted the spreadsheet into a web app to make it easy to play with the numbers.

It is interesting to see how the different variables affect the horsepower needed to move a mass up a hill. I can not attest to the accuracy of the numbers, as all I did was convert the formulas. There are also some interesting links that are helpful in understanding some of the numbers.

Interesting worksheet.

It takes more than twice as much additional HP to increase 5 mph from 75 to 80 a it would for the same increase from 45 to 50. It proves why a 5 mph drop in speed from 80 would save more fuel than a similar drop from 50.

HP required to go 70 is 2.1 times that required to go 55 assuming a 5 mph headwind on a flat grade.
