You need the radius or diameter of the blender. You need the radius or diameter of the blender. If it's 6 inches. Your answers would be. 71.36 mph @ 4,000 rpm. 356.81 mph @ 20,000 rpm. 3,711 mph if the last one is 208,000 rpm.
Definition of pK a and K a. The definition of K a is: [H + ] . [B] / [HB], where B is the conjugate base of the acid HB. The pK a value is defined from K a, and can be calculated from the K a value from the equation pKa = -Log 10 (K a).
Definition of pK. pK is a negative logarithmic scale of any rate constant. One of the most important examples of pK is pK a, the scale of relative acid strength. pK a is the negative log of the acid dissociation constant (pKa=-log([A-][H+]/[HA])).The Henderson-Hasselbalch equation relates pK a and pH to the relative concentrations of an acid and conjugate base in solution (pH=pKa+log([A-]/[HA])) .ne of the most important examples of pK is pK a, the scale of relative acid strength.
