Calculate the charge developed on a vessel being filled with carbon black by pouring from another open vessel.

Calculate the charge developed on a vessel being filled with carbon black by pouring from another open vessel.

Assume the vessel has a volume of 1.89 m^3 and the feed rate is 0.1 kg/s. Identify the accumulated charge and the energy, and then determine whether the energy exceeds the MIE of dusts.

Does the lower charge rate loweres the potential hazard?
