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).
An example of ammonium and ammonia and how K a and pK a values are used is given below. The Ka value of NH 4 + is 5.75. 10 -10 under ideal conditions at 25 degrees Celsius. This K a value is used to determine how much of the NH 4 + is dissociated into its conjugate base NH 3 by the reaction NH 4 + 3 + H + .
