What Is Transient Conduction Mcq?


Answer» a. conduction when temperature at a point varies with time. Explanation: the term transient or unsteady state designates a phenomenon which is time dependent.



Which of the following is called wiped film evaporator?

Agitated thin film evaporator


What is conduction Mcq?

Conduction MCQ Question 2 Detailed Solution

It is defined as a process of preventing the flow of heat from the body by applying insulator materials to the surface which controls the rate of heat transfer.


What is steady-state in conduction?

Steady-state conduction occurs when the temperature at all locations in a substance is constant with time. Thermal conductivity is an important property of matter. It accounts for the heat conducting ability of a substance and depends both on the particular substance involved and on the state of that substance.


What is transient conduction Mcq?

Answer» a. conduction when temperature at a point varies with time. Explanation: the term transient or unsteady state designates a phenomenon which is time dependent.


What is example of conduction?

A common example of conduction is the process of heating a pan on a stove. The heat from the burner transfers directly to the surface of the pan.


Which of the following is not a method of heat transfer Mcq?

So Radiation, Conduction and Convection are 3 basic types of heat transfer and induction is not a mode of heat transfer.


What is heat transfer through conduction?

Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. Conduction occurs more readily in solids and liquids, where the particles are closer together than in gases, where particles are further apart.


Which of the following is a method of heat transfer Mcq?

Explanation: There are three methods of heat transfer between the two systems. They are conduction, convection, and radiation. Conduction is a method of heat transfer in solids and heat transfer takes place without the movement of particles.


How many types of convection process are there?

There are two types of convection: natural convection and forced convection. Natural convection is produced by density differences in a fluid due to temperature differences (e.g., as in “hot air rises”).


What does H stand for in convection?

h: heat transfer coefficient, W/(m2•K) ΔT: difference in temperature between the solid surface and surrounding fluid area, K. It is used in calculating the heat transfer, typically by convection or phase transition between a fluid and a solid.


What does the transient conduction mean?

During any period in which temperatures changes in time at any place within an object, the mode of thermal energy flow is termed transient conduction. Another term is "non-steady-state" conduction, referring to the time-dependence of temperature fields in an object.


What is heat transfer in Mcq?

Explanation: Heat transfer is a branch of thermal engineering which deals with the study of transfer of energy from a high-temperature reservoir to low-temperature reservoir. 2.


What is pin fin?

Pin fins are used to increase heat transfer from heated surfaces to air. Industrial experience has shown that for the same surface area, pin fins can transfer considerably more energy than straight fins. The analysis of a single pin fin is well known.


How many types of convection process are there Mcq?

three types


Which of the following is the method of heat transfer?

Heat is transferred via solid material (conduction), liquids and gases (convection), and electromagnetical waves (radiation). Heat is usually transfered in a combination of these three types and seldomly occurs on its own.


Which of the following is the fastest process of heat transfer?

radiation
