Chemical Engineering

Fluid :- Fluid is a sustance which is capable of flowing and deforms continuously under the action of shearing stress.      Fluid may be divided into three types:- a. Liquid. B. Vapours. C. Gases. Liquid : Liquids offer great resistance to compression and are not much affected by chance of temperature. lt is practically incompressible. Liquids can take the shape of the container. Vapours : vapours are highly compressible  any change in temperature and pressure will change their density(mass/volume). We can also  condensate vapours by condensation(it is a process when vapours comes into liquid form with the help of cold medium). Gas : It is also highly compressible and also change its density when temperature and pressure will change. In gases the mean distance between the molecules is very large as compare to liquid and solid and the intermolecular forces of cohesion are less. Fluids can further classified as; 1. Ideal fluid 2. Real fluid ● Ideal fluid :- It is on

In this post we will discuss about thermodynamics. so let's start. Thermodynamics is the branch of science which deals with the transformation of energy of all kinds from one form to another form and we can also say that it is mainly the study of heat and work effect. In the study of thermodynamics we read, basically four laws : the zeroth, the first, the second, the third law of thermodynamics. The laws of thermodynamics apply to the matter in bulk and not to individual atoms or molecules.these laws are based on a large number of experimental observation  and logical reasoning like all physical laws(Boyles, charles, etc). The laws of thermodynamics have no mathematical proof and have not so far violated. So, why do we study thermodynamics? or what is the utility of this subject?   Basically thermodynamics tells us whether a given process(including chemical reaction) is possible or not, under a given set of condition (e.g. temperature, pressure, etc).It provides infor

  As we know that Air pollution is basically the presence of foreign substance in air in excessive concentration which adversely affects the well being of the individual or cause damage to property. Wherever we live, the air is contaminated to some degree by human activity.The earliest pollutants noted in the atmosphere were of natural origin ; like smoke , fumes, ash, and gases from volcanoes and forest fires or sand and dust from with storms or any other natural sources. But real problem arise when human induced or anthropogenic source started emitting pollution. Which are not good for human being.   According to WHO ( world health organization) is defined as "the substance put into air by human activity which directly effect to his health, vegetable, property etc". We have a many historical overview of Air pollution some are given below ; 1. London smog in Dec. 1952 coal induced smog is formed by interaction of sulphur dioxide, smoke and water to form sulphuri

After industrial revolution in London (U.K) lot of industrial work established due to which excessive environment. Pollution become a major problem in London so government of United Kingdom appointed to check and gives suggestion to reduce the pollution emitted by the factories. There he absorbed some common factor/operation in various factories like following of fluid, exchange of heat, exchange of mass, he prepared 12 lectures on common operation and started teaching them in United State/Kingdom. After that come to known that these lecture and that unit operation in 1957 there was a conference in Amsterdam where the little of conference was Chemical Reaction Engineering and they wanted to concentrate only on reaction . J.C Vlagter gave this name CRE in 1958 in Amsterdam When we apply all Engineering principle to Chemical Reaction Engineering. Application of CRE. ● Waste Treatment. ● Living System. ● Manufacturing of Pharmaceutical. ● Manufacturing of Chemical. ● Modeling of

  Petro leum: we know that liquid fuels are used extensively these days in industrial and domestic areas. Today we will discuss about liquids fuel and we hear about Petroleum, which is a largest source of liquid fuel.             The Petroleum means rock oil or it is also known as mineral oils. Crude oil and petroleum is a basic raw material for refining industries.it occurs in the earth crust mostly in sedimentary rocks in all possible state(gas, liquid and solid). It is dark colour viscous liquid colour varies from light brown to dark brown.petroleum is a mixture of various hydrocarbons mainly ' PONA' .

Heat : Heat is a form of energy that can be transfer from a body at higher temperature to lower one because of temperature difference, and the energy transfer stop when the two medium reach the same temparature or equilibrium.
