Does juice temperature increase with increasing convective heat transfer coefficient at any constant kettle surface temperature?
Yes, the juice temperature increases with an increasing convective heat transfer coefficient at any constant kettle surface temperature. The convective heat transfer coefficient represents the efficiency of heat transfer from the kettle to the juice. As the convective heat transfer coefficient rises, more heat is transferred from the kettle surface to the juice per unit of time. This increased efficiency results in a faster temperature rise in the juice. Therefore, a higher convective heat transfer coefficient enhances the overall heating process, leading to a greater temperature increase in the juice even when the kettle surface temperature remains constant.
Does every transfer decrease momentum?
No. Total momentum always remains constant. Therefore, if the momentum of one object decreases, the momentum of another must needs increase.
What is the convective heat transfer coefficinet for air at atmospheric condition and how it change with other factors?
The convective heat transfer of any fluid is dependent on its velocity, viscosity...and other properties. The higher the velocity the higher the coefficient. Generally indoor convective heat transfer of air is approximately 40 W/m2.K It varys depending on wind conditions, generally within the range of 10-100 W/m2.K
What is the Heat transfer coefficient for aluminiun oxide?
around 40 W/mK
Why does heat move by conduction in an empty space?
If you are asking about a box filled with a gas, then heat transfer can modeled as conduction through a solid. The requirement would have to be no fluid flow (obviously there is movement at the micro level), and the conductive heat transfer coefficient would be very low.Convection heat transfer is dependent on that conductive heat transfer coefficient of the liquid and is based on something called the Nusselt number.If you are asking about heat transfer through a completely void space, then heat would travel by means of radiation.

What is the role of thermal energy in osmosis?
The speed of an osmotic transfer can increase as temperature increases. An increase in thermal energy will increase the movement of molecules both in the liquids, and of the semipermeable membrane, resulting in an increased flow. An increase in thermal energy may also lower the viscosity of a liquid, increasing it's rate of flow.

What is the heat transfer coefficient for copper in SI units?
400W/mK
Does every transfer decrease momentum?
No. Total momentum always remains constant. Therefore, if the momentum of one object decreases, the momentum of another must needs increase.
How flooding in distillation column control?
flooding in disillation column is control: 1) to reduce total crude charge, 2)to decrease the transfer temperture, 3) increase the tower reflux, 4) increase the tower pressure.

What is the value of an overall heat transfer coefficient in an engine oil cooler?
I have a book (Introduction to heat transfer - Bergmann), there is an example of an oil cooler cooled by air (crossflow heat exchanger with both fluids unmixed). There is written: "... with an overall heat transfer coefficient of 53 W/(m²*K)."
