“A brief history of chemical warfare” By Harold Maass For more than 2‚000 years. As early as 600 B.C.‚ the Athenians poisoned the wells of the Spartans‚ who later tried lobbing burning sulfur pitch over the walls of Athens‚ hoping to fill the city with toxic smoke. Genghis Khan used that same trick‚ catapulting burning sulfur pitch during his siege of fortified cities around A.D. 1200. Over the centuries‚ various armies put poisons on arrows and in bullets to make them more lethal. But it wasn’t

Continuity Equations Continuity equation is a equation that explain the transport of a conserved quantity. Since‚ mass‚ energy‚ momentum are conserved under respective condition‚ a variety of physical phenomena may be describe using continuity equations. By using first law of thermodynamics‚ energy cannot be created or destroyed. It can only transfer by continuous flow. Total continuity equation (TCE)‚ component continuity equation(CCE) and energy equation(EE) is applied to do mathematical model
