Questions & Step-by-Step Solutions
Which of the following factors does NOT affect the rate of heat transfer by convection?
Step 1: Understand what convection is. Convection is the process of heat transfer through fluids (liquids and gases) where warmer areas of a liquid or gas rise and cooler areas sink.
Step 2: Identify the factors that affect convection. These include temperature difference, fluid velocity, and the properties of the fluid (like viscosity and thermal conductivity).
Step 3: Recognize that material density is a property of the fluid but does not directly influence how quickly heat is transferred by convection.
Step 4: Conclude that since material density does not directly affect the rate of heat transfer by convection, it is the correct answer to the question.
