Some people calls it "Dual Signals Control". In an early 1960, a company called Wallace & Tiernan introduced a control scheme called "Compound Loop Control" and used it to control chlorine in a chlorination process. This control strategy based upon two independent signals...
Has anyone know the matimatically details of "Compound Loop" control for water disinfection? I am appreciated if anyone can give me an answer or direct me of where to look for the info.
Thanks,

power = vi = i^2xr
for both ac and dc, when circuit is purely resistive ..i.e no active elements such as capacitor or inductance...then no phase angle exists... then 4500^2 multiply by the resistance is the power in watts ... resistance will change with temperature though..probably dramatically...
