5 points2.rThe formula for blood flow rate is given byF = P1 – P2, where F is the flow rate, pı the initialpressure, p2 the final pressure, and r the resistancecreated by blood vessel size. Which formula cannot be derived from the given formula?A. Pi = Fr + P2B. P2 = pi - Frc. r = F(p2 - P1)PL-P2D. r =F
