## Crushing Efficiency Solution

STEP 0: Pre-Calculation Summary
Formula Used
Crushing Efficiency = (Surface Energy Per Unit Area*(Area of Product-Area of Feed))/Energy Absorbed By Material
ηc = (es*(Ab-Aa))/Wh
This formula uses 4 Variables
Variables Used
Surface Energy Per Unit Area - Surface energy per unit area is the excess energy at the surface of a material compared to its volume. (Measured in Newton per Meter)
Area of Product - Area Of Product is the area per unit mass of the milled material. (Measured in Meter^2/Kilogram)
Area of Feed - Area of Feed is the area per unit mass of the feed. (Measured in Meter^2/Kilogram)
Energy Absorbed By Material - Energy Absorbed By Material is the energy that the material particles acquires while the material is being crushed . (Measured in Joule per Kilogram)
STEP 1: Convert Input(s) to Base Unit
Surface Energy Per Unit Area: 1 Newton per Meter --> 1 Newton per Meter No Conversion Required
Area of Product: 8 Meter^2/Kilogram --> 8 Meter^2/Kilogram No Conversion Required
Area of Feed: 7 Meter^2/Kilogram --> 7 Meter^2/Kilogram No Conversion Required
Energy Absorbed By Material: 20 Joule per Kilogram --> 20 Joule per Kilogram No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
ηc = (es*(Ab-Aa))/Wh --> (1*(8-7))/20
Evaluating ... ...
ηc = 0.05
STEP 3: Convert Result to Output's Unit
0.05 --> No Conversion Required
0.05 <-- Crushing Efficiency
(Calculation completed in 00.000 seconds)
