Is there a pulley ratio formula?

Jun 27, 2007 by MisquetoFarmer | Posted in Physics

I need a pulley ratio formula that would allow me to calculate rpms of one pulley to another pulley of a different size. The formula will be used to calculate the mechanical needs of a wind driven water pump so no engines will be used in this process.

the driver pulley divided by the driven pulley. this gives you the ratio. as
driver pulley is 400cm, the driven pulley is 200cm, these are diameter measurements.
400/200=2 the answer is 1:2 being every one revolution of the 400cm driver

Measuring technological progress
Many sociologists and anthropologists have created social theories dealing with social and cultural evolution. Some, like Lewis H. Morgan, Leslie White, and Gerhard Lenski, declare technological progress to be the primary factor driving the development of human civilization. Morgans concept of three major stages of social evolution (savagery, barbarism, and civilization) can be divided by technological milestones, like fire,...
