Rock Removal Rate Formula
\( q_r \;=\; b_d^2 \; R \;/\; 11000 \) (Rock Removal Rate) \( b_d \;=\; \sqrt{ q_r \; 11000 \;/\; R } \) \( R \;=\; q_r \; 11000 \;/\; b_d^2 \)
Symbol	English	Metric
\( q_r \) = Rock Removal Rate	\(ft^3 \;/\; min\)	-
\( b_d \) = Bit Diameter	\(in\)	-
\( R \) = Penetration Rate	\(ft \;/\; hr\)	-

Drilling rock removal rate, abbreviated as \(q_r\), is the efficiency at which rock material is removed through drilling operations.
