The accuracy of these mathematical relations has previously been demonstrated in our previous study [20], and hence presenting its validation stage is excluded here for the sake of brevity. The main equations used to calculate the main performance and parameters of the RO unit are listed in ...
Coulomb's law made it possible to calculate the electrostatic force between any two charged objects, but it didn't reveal the fundamental nature of those charges. What was the source of the positive and negative charges? As we'll see in the next section, scientists were able to answer tha...
