η_c = (e_s*(A_b-A_a))/W_h
This formula uses 5 Variables

Variables Used

Crushing Efficiency - Crushing Efficiency is defined as the ratio of surface energy created by crushing to the energy absorbed by the solid .
Surface Energy per Unit Area - (Measured in Joule per Cubic Meter) - Surface Energy per Unit Area is the excess energy at the surface of a material compared to its volume.
Area of Product - (Measured in Square Meter) - Area Of Product is the area per unit mass of the milled material.
Area of Feed - (Measured in Square Meter) - Area of Feed is the area per unit mass of the feed.
Energy Absorbed by Material - (Measured in Joule) - Energy Absorbed by Material is the energy that the material particles acquires while the material is being crushed.

STEP 1: Convert Input(s) to Base Unit

Surface Energy per Unit Area: 17.5 Joule per Cubic Meter --> 17.5 Joule per Cubic Meter No Conversion Required
Area of Product: 100 Square Meter --> 100 Square Meter No Conversion Required
Area of Feed: 99.54 Square Meter --> 99.54 Square Meter No Conversion Required
Energy Absorbed by Material: 22 Joule --> 22 Joule No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

η_c = (e_s*(A_b-A_a))/W_h --> (17.5*(100-99.54))/22

Evaluating ... ...
