The peak overpressure expected as a result of the explosion of a tank in a plant facility is approximated by the equation logP=7.10941.8logr Where P is the overpressure in N/m2, and r is the distance from the blast in meters. The plant employs 500 people who work in an area from 3 to 150m from the potential blast site. Estimate the number of fatalities due to lung hemorrhage as a result of this blast. Assume there are 5 shells around the center and the people are evenly distributed through the area
