Question

which of the following terms is defined as the rate at which a planar flame moves through a stationary, quiescent flammable mixture of infinite extent?

Answer 1

The rate at which a planar flame moves through a stationary, quiescent flammable mixture of infinite extent is known as the flow rate.

Step-by-step explanation:

The term that is defined as the rate at which a planar flame moves through a stationary, quiescent flammable mixture of infinite extent is flow rate.

The flow rate is the volume of fluid passing by a location through an area during a period of time. In this case, it refers to the rate at which the flame moves through the mixture.

For example, in the case of a Bunsen burner flame, the velocity profile across the tube affects the shape of the flame.

Answer 2

The term that is defined as the rate at which a planar flame moves through a stationary, quiescent flammable mixture of infinite extent is flow rate.

Step-by-step explanation:

The term that is defined as the rate at which a planar flame moves through a stationary, quiescent flammable mixture of infinite extent is flow rate.

The flow rate, represented by the symbol Q, is the volume of fluid passing by a location through an area during a period of time. It is a fundamental concept in fluid dynamics and is used to describe the movement of fluids.

In the context of the question, the flame of a Bunsen burner can be considered a planar flame that moves through a flammable mixture. The flow rate of the flammable mixture would determine how quickly the flame moves through the mixture.
