Test: Boiling - Question 1

Boiling refers to a change from the

Detailed Solution: Question 1

Boiling is a convective heat transfer process that is associated with change in the phase of a fluid.

Test: Boiling - Question 2

The boiling process has wide-spread applications in
(i) Production of steam in nuclear and steam power plants for generation and for industrial processes and space heating
(ii) Absorption of heat in refrigeration and air-conditioning systems
(iii) Concentration, dehydration and drying of foods and materials
Identify the correct statements

Detailed Solution: Question 2

Boiling constitutes the convective heat transfer process that involves a phase change from liquid to vapor state.

Test: Boiling - Question 3

Maximum heat transfer rate in a modern boiler is about

Detailed Solution: Question 3

Greater importance has recently been given to the boiling heat transfer.

Test: Boiling - Question 4

Which type of boiling occurs in steam boilers employing natural convection?

Detailed Solution: Question 4

The liquid above the hot surface is essentially stagnant and the only motion near the surface is because of free convection.

Test: Boiling - Question 5

In which type of boiling the fluid motion is induced by external means?

Detailed Solution: Question 5

The liquid is pumped and forced across the surface in a controlled manner.

Test: Boiling - Question 6

The temperature of the liquid is below the saturation temperature and boiling takes place only in vicinity of the heated surface. This type of boiling is known as

Detailed Solution: Question 6

The vapor bubbles travel a short path and then vanish, apparently they condense in the bulk of the liquid which is at a temperature less than the boiling point.

Test: Boiling - Question 7

In which type of boiling the temperature of the liquid exceeds the saturation temperature?

Detailed Solution: Question 7

The vapor bubbles generated at the solid surface are transported through the liquid by buoyancy effects and eventually escape from the surface.

Test: Boiling - Question 8

The phenomenon of stable film boiling is referred to as

Detailed Solution: Question 8

This is the region of stable film boiling.

Test: Boiling - Question 9

For water evaporating at atmospheric pressure, the burnout occurs at temperature excess slightly above

Detailed Solution: Question 9

The burnout point on the boiling curve represents the point of maximum heat flux at which transition occurs from nucleate to film boiling.

Test: Boiling - Question 10

The boiling phenomenon is known to occur in how many forms?

Detailed Solution: Question 10

Pool, forced convection, subcooled and saturated boiling.
