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).
The pKa is a measure of the weak acidâs ability to ionize. Thus, pH and pKa seem like very similar terms, and it is important not to get them confused. Remember, pH is a direct measure of the H+ concentration, while pKa represents a particular acidâs ability to ionize (dissociate into ions, including H+).
