d_b = (B_L*33)*sqrt((c*D_f*EV)/(D_p*s))
This formula uses 1 Functions, 7 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Diameter of Drill Bit - (Measured in Millimeter) - Diameter of Drill Bit in Langefors’ Formula relates rock drillability to bit diameter, expressing the effect of diameter on drilling efficiency and performance.
Burden in Langefors' Formula - (Measured in Millimeter) - Burden in Langefors' Formula is the ratio of explosive weight to rock mass, determining efficient rock fragmentation in blasting operations.
Rock Constant - Rock Constant is a fundamental geological parameter representing Earth's average continental crust composition, vital for understanding planetary evolution and geodynamics.
Degree of Fraction - Degree of Fraction is used for hole characteristics.
Ratio of Spacing to Burden - Ratio of Spacing to Burden is the relationship between the gap size and load-carrying capacity in structural elements.
Degree of Packing - (Measured in Kilogram per Cubic Decimeter) - Degree of Packing is the loading weight per unit of nominal volume.
Weight Strength of Explosive - Weight Strength of Explosive the measure the absolute amount of energy available in each gram of explosive.

STEP 1: Convert Input(s) to Base Unit

Burden in Langefors' Formula: 0.01 Meter --> 10 Millimeter (Check conversion here)
Rock Constant: 1.3 --> No Conversion Required
Degree of Fraction: 2.03 --> No Conversion Required
Ratio of Spacing to Burden: 0.5 --> No Conversion Required
Degree of Packing: 3.01 Kilogram per Cubic Decimeter --> 3.01 Kilogram per Cubic Decimeter No Conversion Required
Weight Strength of Explosive: 5 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

d_b = (B_L*33)*sqrt((c*D_f*EV)/(D_p*s)) --> (10*33)*sqrt((1.3*2.03*0.5)/(3.01*5))

Evaluating ... ...

d_b = 97.7125589985572

STEP 3: Convert Result to Output's Unit

0.0977125589985572 Meter -->97.7125589985572 Millimeter (Check conversion here)

FINAL ANSWER

97.7125589985572 ≈ 97.71256 Millimeter <-- Diameter of Drill Bit
