### How to Calculate Head Loss Hunker

Step 3. Calculate the static head loss based on 100 feet of elevation. The conversion factor for water at normal ambient conditions of 60 degrees Fahrenheit is 2.31 feet of elevation per pound per square inch water pressure. Dividing the 100 feet of elevation by 2.31 feet per psi yields a head loss of 43.29 psi.

Diagram 1 shows how friction changes, as a function of speed, in a bearing with a given lubricant. Four zones are distinguishable Zone 1 Boundary lubrication condition, in which only the asperities carry the load, and so friction between the moving surfaces is high.; Zone 2 Mixed lubrication condition, in which a separating oil film carries part of the load, with fewer asperities in

Chat Online### How to calculate friction on a spinning ball on the ground?

Also the surface of the ball is never perfectly flat, so there will always be friction between the surface of the ball and the surrounding air. So for calculating the friction, you need to know the exact area in which the ball and the ground touches. And you have to include the friction between the moving surface of the ball and the air.
