Hardness of work material Solution

STEP 0: Pre-Calculation Summary
Formula Used
brinell_hardness = Density/(12*(Material removal rate/(Empirical constant*No. of abrasive particles impacting per unit time*Mean diameter of abrasive particles^3*Velocity^(3/2)))^(4/3))
HB = ρ/(12*(Zw/(A0*N*d^3*v^(3/2)))^(4/3))
This formula uses 6 Variables
Variables Used
Density - The density of a material shows the denseness of that material in a specific given area. This is taken as mass per unit volume of a given object. (Measured in Kilogram per Meter³)
Material removal rate - Material removal rate (MRR) is the amount of material removed per time unit (usually per minute) when performing machining operations such as using a lathe or milling machine. (Measured in Meter³ per Second)
Empirical constant- The Empirical constant is a self determined constant whose value is accessible from table of such constants. This constant is used to calculate the intrinsic carrier concentration.
No. of abrasive particles impacting per unit time- No. of abrasive particles impacting per unit time
Mean diameter of abrasive particles - Mean diameter of abrasive particles is the mean calculated from sampling method. (Measured in Millimeter)
Velocity - Velocity, in physics, is a vector quantity (it has both magnitude and direction), and is the time rate of change of position (of an object). (Measured in Meter per Second)
STEP 1: Convert Input(s) to Base Unit
Density: 997 Kilogram per Meter³ --> 997 Kilogram per Meter³ No Conversion Required
Material removal rate: 1 Meter³ per Second --> 1 Meter³ per Second No Conversion Required
Empirical constant: 100 --> No Conversion Required
No. of abrasive particles impacting per unit time: 5 --> No Conversion Required
Mean diameter of abrasive particles: 1 Millimeter --> 0.001 Meter (Check conversion here)
Velocity: 60 Meter per Second --> 60 Meter per Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
HB = ρ/(12*(Zw/(A0*N*d^3*v^(3/2)))^(4/3)) --> 997/(12*(1/(100*5*0.001^3*60^(3/2)))^(4/3))
Evaluating ... ...
HB = 0.00118697913660922
STEP 3: Convert Result to Output's Unit
0.00118697913660922 Pascal -->1.21038187006705E-10 Kilogram-Force per Square Millimeter (Check conversion here)

What is Abrasive Jet Machining ?

Abrasive Jet Machining is a process that uses a very high speed (supersonic about 2.5 Mach number) water jet mixed with abrasives to cut any type of material without, in any way, affecting the work material or the environment. The AJM machines aim a highly focused, supersonic stream of water at the material such that it can cut composites smoothly by eroding them without generating any heat. Thus the AJM process eliminates all the thermal and mechanical distortion caused by conventional cutting methods. Also the water jet nozzle can be directed at any angle to the material thereby allowing for angled cuts. For cutting soft materials such as textiles and food stuffs, pure water without any abrasives is used.
