CoachFree convection is a natural process where fluid motion is generated by density differences due to temperature variations, without any external influence. Forced convection, on the other hand, is when fluid motion is induced by an external force like a fan, pump, or compressor, leading to enhanced heat transfer rates.

What does free and forced convection mean?
Free convection refers to the natural flow of fluid (liquid or gas) caused by density differences due to temperature variations. Forced convection, on the other hand, refers to the fluid flow driven by an external force, such as a pump or a fan.
Difference between free vibrations and forced vibrations?
Free vibrations occur when a system oscillates at its natural frequency without any external force, while forced vibrations occur when a system is forced to oscillate by an external force at a frequency that may be different from the system's natural frequency. Free vibrations eventually dampen out due to energy losses, whereas forced vibrations can be sustained by the external force.
What is the difference between convection and convection currents?
Convection is the transfer of heat through the movement of a fluid, such as air or water. Convection currents refer to the circular motion created when warmer, less dense fluid rises and cooler, denser fluid sinks, driving the transfer of heat. Convection currents are a result of convection in fluids.
What factor free covection heat flow depends?
Free convection heat flow depends on factors such as the temperature difference between the object and the surrounding fluid, the fluid properties (such as viscosity and density), the surface area of the object, and the shape of the object. These factors influence the rate at which heat is transferred from the object to the fluid through convection.
What is the difference between free fall and jumping out a plane?
free fall doesn't involve jumping out a planes
