A broad question, so I will give a broad answer. A driving force is needed and what drives heat transfer is simply temperature differences between two bodies.
The mechanism at say a molecular level is really just the exchange of the energy from molecules to molecules. Higher energy molecules will collide with lower energy molecules and voila, you have heat transfer.
What else can I help you with?
What are the advantages disadvantages of concentric tube heat exchanger?
Advantages: Simplicity of design; Easy to clean and maintain; ideal for fluids that cause fouling. Disadvantages: Length cannot be extended beyond a limit Rate of heat transfer is low + high cost when considering amt of heat transfer. Heat looses occur from the outer shell.
What is interfacial area?
when two material are brought to contact,so the space where they made contact is called interfacial area,it is usually considered in heat transfer calculation
Why use soot blower in boiler?
Soot blowers are used in boilers to remove accumulated soot and ash from the heat transfer surfaces, which helps maintain optimal heat transfer efficiency. Regular soot removal prevents the formation of insulating layers that can reduce boiler performance and increase fuel consumption. By minimizing soot buildup, soot blowers also aid in preventing overheating and potential damage to boiler components, thereby enhancing overall operational safety and reliability.
How steam required for steam tracing of jacketed lines is calculated how much steam required for sulfur melting?
The steam required for steam tracing is calculated on the basis of the amount of heat transfer that is required or the temperature that you want to maintain with the help of steam. It also depends on the pipe material through which the steam is passing,the condition of the steam that whether it is saturated or superheated etc. Overall heat transfer cofficient is calculated considering all the factors like fouling or scaling,inside and outside dia. , surface area etc. After calculating the amount of heat to be transferred, the requirement of rate of steam is calculated. Generally, Low pressure steam is used as it has got more latent/Sensible heat as compared to MP or Superheated steam.
Can you major in chemistry and become a chemical engineer?
It is possible but would be tough for a person from chemistry background. This is since he has to go into the basic technical aspects such as fluid mechanics, heat transfer, engineering thermodynamics, calculus and process design without which a chemical engineer is impossible.
How heat transfer is controlled?
There is a special mechanism that controls heat transfer.
What is the heat transfer mechanism responsible for the daily wind cycle?
heat transfer through convection.
Which mechanism is not a way to transfer heat?
Fusible link
What is the least important mechanism of heat transfer in the whole atmosphere?
Conduction is the least important mechanism of heat transfer in the whole atmosphere. It is less efficient in transferring heat because the air is a poor conductor, and convection and radiation are the dominant mechanisms of heat transfer in the atmosphere.
What is a mechanism of heat transfer that involves direct contact?
conduction
What is the major heat transfer mechanism within solids?
conduction
What are the three major mechanism of heat transfer?
The three major mechanisms of heat transfer are conduction, convection, and radiation. Conduction is the transfer of heat through direct contact between materials. Convection is the transfer of heat through the movement of fluids. Radiation is the transfer of heat through electromagnetic waves.
What are the mechanism of heat transfer?
Radiation, conduction, and convection You may want to look on this website!
What type of heat transfer occurs between a pan and a hot stove burner the pan is sitting on?
The predominant heat transfer mechanism used to transfer heat from the pan to the stove burner is radiation.
What is the least important mechanism of heat transfer?
Conduction is typically considered the least important mechanism of heat transfer because it is generally slower and less effective compared to convection and radiation. Conduction requires direct contact between molecules or particles to transfer heat, making it less efficient for transferring heat over long distances or through fluids.
