HOMEWORK IV-TSCREEN (DUE ON Mar 22) Chlorine Gas Leak As shown in the following figure, chlorine gas stored in a tank at 6.8 atm and 320 K is released through a 2.8 cm hole. The release does not have a vertically directed jet. 1) Which submodel in TSCREEN should be selected for calculation? 2) What is the distance to the maximum ground level concentration? 3) What is the concentration at that point? 4) Draw a graph of ground level centerline chlorine concentration with distance from 30 m to 1000 m.
