Question

Which of the following statement regarding heat transfer through stationary fluid is correct? Select one: a. Conduction occurs when temperature gradient exists in stationary fluid Ο b. Convection occurs when temperature gradient exists in stationary fluid Ο c. Radiation occurs when temperature gradient exists in stationary fluid d. No heat transfer occurs when temperature gradient exists in stationary fluid

Answer 1

b. Convection occurs when temperature gradient exist in stationary fluid.

Step-by-step explanation:

Convection : heat transport through fluid movement; It also occur when there is heat exchange between a solid and a fluid.

there are two types:

• free convection: Only natural forces intervene ( gravity ).
• forced convection: designed by a man.

Q = h * A * ΔT
