Thermal Processing and Sterilization

Liquid egg with electrical conductivity $\sigma = 1.2\text{ S/m}$ is subjected to an electric field $E = 2000\text{ V/m}$ ($E^2 = 4 \times 10^6\text{ V}^2/\text{m}^2$). The volumetric heat generation rate $q''' = \sigma E^2 = 1.2 \times 4 \times 10^6$ in $\text{MW/m}^3$ ($10^6\text{ W/m}^3$) is:
