What is the objective of free convection experiment done in your lab?

The objective of the lab is to introduce students to experimental and analytical methods of free convective heat transfer analysis including: the application of similarity solutions, experimental measurement, and the analytical and experimental determination of the convective heat transfer coefficient.

What is the conclusion of convection experiment?

Conclusion: In fluids, such as water and air, convection is a much more efficient method of heat transfer than conduction. This difference in efficiency produced the dramatic difference in the time required to melt the ice.

What process is taking place in the convection experiment?

Download printable Experiment Sheet here. Convection is the process of heat transfer within a fluid. Over time, this will result in a circular motion of fluid as hot fluid rises and cold fluid sinks. This process in large part is a driver of many of the air and ocean currents we see on Earth.

Where does the introduction of convection take place?

INTRODUCTIONConvection is the movement of molecules within fluids (i.e. liquids, gases). It cannot take place insolids, since either bulk current flows or significant diffusion can take place in solids. Convection isone of the major modes of heat transfer and mass transfer.

What’s the best way to experiment with convection?

Convection. A popular experiment involves a large transparent bowl or container of ice water. Combine hot water and a few drops of food coloring into a small transparent container, such as a perfume bottle. Place the small container inside of the bowl, and observe the convection currents.

What is the purpose of the heat transfer experiment?

OBJECTIVE: The purpose of this experiment is to study experimentally the natural convection pipe flows at different heating level. INTRODUCTION: There are certain situations in which the fluid motion is produced due to change in density resulting from temperature gradients, which is the heat transfer mechanism called as free or natural convection.

How is convection a type of heat transfer?

Convection is one of three main types of heat transfer. The other two being radiation and conduction. Convection is the transfer of heat by the movement of heated particles into an area of cooler particles. You can experience convection when you light a match. The air directly above the lit match is always hotter than the air around the match.
