To calculate the kinetic energy, first convert km/h to meters per second: 40km/h = 11.11 m/s. Using the first kinetic energy equation above, replace the values for m and v and get KE = 2200 · (11.11) 2 / 2 = 135775.3 Joules or 135.7753 kiloJoules. Example 2: A ball which weighs 500 grams has a kinetic energy of 500 J.

We will demonstrate how the calculator works with a simple example: Susan is a 70kg (~154 lbs) woman who walked her dog for exactly 30 min. According to the metabolic equivalent table, walking the dog corresponds to an energy expediture of 3.0 METs. In order to perform the calculation, all we have to do is to multiply the weight (kg), the ...
The formula for critical speed is CS = 1/2π √ (g/ (R-r) where g is the gravitational constant, R is the inside diameter of the mill and r is the diameter of one piece of media. This reduced to CS = 265.45/√ (R-r). Dry mills typically operate in the range of 50%-70% of CS and most often between 60%-65% of CS.
