Heat Transfer Assignment Help

Heat transfer comes under the purview of thermodynamics. To put it simply, Heat transfer deals with the amount of heat transfer that takes place in a system from one state of equilibrium to another. This might not take into account the time taken for the heat transfer or the amount of heat transferred over a period of time. Why does heat transfer take place? Heat is a form of energy that moves along temperature difference. Heat transfer is energy transfer from [...]

Bernoulli’s Theorem in Chemical Engineering

Bernoulli’s Theorem in fluid dynamics is one of the important discoveries. The relation among pressure, velocity, and elevation in a moving fluid, the compressibility and viscosity of which are negligible and the flow of which is steady or laminar. The Theorem was first derived in 1738 by Swiss mathematician Daniel Bernoulli. The theorem states that, in effect, that the total mechanical energy of the flowing fluid, comprising the energy associated with fluid pressure, the gravitational potential energy of elevation [...]

Understanding Heat Transfer in Chemical Engineering

Chemical Engineering Heat Transfer The field of heat transfer explores the rate at which heat flows from a region of high temperature to one of low temperature. Heat flow occurs as molecules transfer their thermal energy, in the form of molecular motion, to nearby lower energy molecules or by fast moving molecules moving to another region of the system. The mechanisms of heat transfer can be categorized as occurring by convection, conduction, or radioactive processes. Convection occurs in a liquid [...]

Distillation in Chemical Engineering

Distillation is the process of separation of volatile liquid from non-volatile substance or more frequently, the separation of two or more liquids in different volatility. If only one component of a mixture is volatile, there is no difficulty in obtaining it in a pure state by distillation and in many cases the constituents of a mixture of two or more volatile liquids may be separated – though frequently at much cost of time and materials. Quantitative Analysis by Distillation: The [...]

Electrochemsitry in Chemical Engineering

Electrochemsitry In solid crystals such as NaCl, electrical charges are localized on those sites that form the lattice. These lattice sites are occupied not by neutral atoms, but by negatively charged chlorine or positively charged sodium ions and the crystal is held together by the columbic forces that exist between all electrically oppositely charged species. The energy of interaction between two particles of charge q1 and q2 at a distance r from one another is given by U12 = [...]

Understanding Mass Transfer in Chemical Engineering

Chemical Engineering Mass Transfer The field of Heat Transfer explores the rate at which heat flows from a region of high temperature to one of low temperature. Heat flow occurs as molecules transfer their thermal energy, in the form of molecular motion, to nearby lower energy molecules or by fast moving molecules moving to another region of the system. The mechanisms of Heat Transfer can be categorized as occurring by convection, conduction, or radiative processes. Convection occurs in a liquid or [...]

Chemical Engineering Thermodynamics

Chemical Engineering Thermodynamics is the study of relationship between heat and work with chemical reactions or with physical changes of state within the confines of the laws of thermodynamics. The subject involves the study of laboratory measurements of various thermodynamic properties and also the study of application of mathematical methods and calculations to the chemical equations. The subject of chemical Thermodynamics is based on the laws of thermodynamics. The study of laws of thermodynamics leads to the derivation of the [...]
