Daniel Bernoulli (Groningen‚ 8 February 1700 – Basel‚ 8 March 1782) was aDutch-Swiss mathematician and was one of the many prominent mathematicians in theBernoulli family. He is particularly remembered for his applications of mathematics to mechanics‚ especially fluid mechanics‚ and for his pioneering work in probability andstatistics. Bernoulli’s work is still studied at length by many schools of science throughout the world. In Physics :- He is the earliest writer who attempted to formulate a kinetic

Shaft rotary kiln The theoretical heat (the standard enthalpy) of reaction required to make high-calcium lime is around 3.15 MJ per kg of lime‚ so the batch kilns were only around 20% efficient. The key to development in efficiency was the invention of continuous kilns‚ avoiding the wasteful heat-up and cool-down cycles of the batch kilns. The first were simple shaft kilns‚ similar in construction to blast furnaces. These are counter-current shaft kilns. Modern variants include regenerative and

This means less energy is needed for the reactions to happen when the collisions occur‚ so more reactions will happen. 5.
