Question
Current-carrying components in high-voltage power equipment must be cooled to carry away the heat caused by ohmic losses. A means of pumping is based on the force transmitted to the cooling fluid by charges in an electric field. The electrohydrodynamic (EHD) pumping is modeled in Figure 6.1. The region between the electrodes contains a uniform charge p0, which is generated at the left electrode and collected at the right electrode. Calculate the pressure of the pump if po = 25 mC/m3 and Vo = 22 kV. please Simplest way to solve
Explanation / Answer
Since ?v is not equal to 0, we apply Poisson
