In summary, the person is new to the forum and is asking about the relationship between air density, air mass flow rate, and heat transfer by convection. They mention that changing the air flow rate affects the heat transfer, mass flow rate, and air density, and they are looking for the specific relationship between these factors. The responder suggests providing a specific situation or model in order to give a more accurate answer.

Hi,

I am new to this Forum... So please let me know this is not the correct sub heading under which i am suppose to post the question...

I would like to the basic relation between the Air density, Air Mass Flow Rate and heat Transferred to air by Convection...

Changing the Air Flow Rate from 0 to say 0.001, the heat transferred, mass flow rate and the air density changes... why and what is the relation?

Your question is too broad. The answer will depend on the situation you have in mind.
If you can refine the situation to one specific model it may be possible to provide you with an answer.

“heat Transferred to air by Convection” or “heat Transferred by air Convection” ?

1. What is thermal engineering?

Thermal engineering is a branch of engineering that deals with the transfer of heat energy between systems or materials. It involves the study of thermodynamics, heat transfer, and fluid mechanics to design and optimize systems that involve heat transfer.

2. What is heat transfer?

Heat transfer is the movement of heat energy from one system or material to another due to a temperature difference. It can occur through three main mechanisms: convection, conduction, and radiation.

3. How is thermal engineering used in everyday life?

Thermal engineering is used in everyday life to design and improve various systems such as refrigerators, air conditioners, heating systems, and cooking appliances. It is also essential in the design of vehicles, buildings, and electronic devices.

4. What are the different types of heat transfer?

The three main types of heat transfer are conduction, convection, and radiation. Conduction occurs when heat is transferred through direct contact between two materials. Convection is the transfer of heat through the movement of fluids. Radiation is the transfer of heat through electromagnetic waves.

5. How is heat transfer calculated in thermal engineering?

The rate of heat transfer can be calculated using various mathematical equations and principles, such as Fourier's law of heat conduction and Newton's law of cooling. Factors such as temperature difference, material properties, and surface area all play a role in determining the rate of heat transfer.
