I need help in the determination of the power drawn by a wet pan mill in gold milling

Short answer is you measure the root-mean-square Amps and Volts going into the motor driving the mill, correct for the motor efficiency (and possibly power factor) and calculate power using equation P = V_rms × I_rms.

Long answer is that pan mills are really mechanically inefficient grinding devices and any power you calculate is probably meaningless.  You can't use Bond's equations to predict anything meaningful with a pan mill.
