| RMP calculations from airborne quantity of toxic substances releases | |||||||
| (LFL DISTANCES FOR FLAMMABLES ALSO) | |||||||
| Chemical name | Ammonia | ||||||
| Molecular weight | 17 | ||||||
| Amount of potential release, U.S. pounds (Adjusted release for LFL calcs.) | 300 | ||||||
| Release time, minutes ( For LFL calculations enter 0.1: averaging time) | 10 | ||||||
| Emission rate, gms/sec | 227 | ||||||
| Wind speed, mi/hr | 3.4 | ||||||
| Wind speed, m/sec | 1.51776 | ||||||
| Toxic endpoint concentration (or LFL for flammables), ppm (or see next row) | |||||||
| Toxic endpoint concentration(or LFL for flammables), mg/L | 0.14 | ||||||
| If above is a 60 min value enter 1; for 30 min value enter 0 (or blank for LFL ) | 0 | ||||||
| Distance to chosen receptor(user receptor), if any,m | 200 | ||||||
| Potential release point height above stack base,m | 1 | ||||||
| Nuetrally buoyant (2), Dense gas (1) or ground-level dispersion (0)- enter | 2 | ||||||
| For urban setting enter 1, for rural setting enter 0 | 0 | ||||||
| For Plot of Concentration vs. Distance, enter min and max distances in meters | 50 | 200 | |||||
