Test: Types of Convection - Question 1
Save

Conduction plus fluid flow in motion is known as

Detailed Solution: Question 1

It is convection i.e. conduction plus some velocity. It is the process of energy transport affected by the mixing of a fluid medium.

Test: Types of Convection - Question 2
Save

How many types of convection are there?

Detailed Solution: Question 2

It is of three types i.e. forced convection, natural convection and mixed convection.

Test: Types of Convection - Question 3
Save

Which of the following heat flow situations pertains to free or natural convection?

Detailed Solution: Question 3

Cooling of billets in atmosphere is both free and natural convection.

Test: Types of Convection - Question 4
Save

Mark the system where heat transfer is given by forced convection

Detailed Solution: Question 4

If the fluid motion involve in the process is induced by some external means then it is called forced convection.

Test: Types of Convection - Question 5
Save

Forced convection in a liquid bath is caused by

Detailed Solution: Question 5

If the fluid motion involve in the process is induced by some external means then it is called forced convection.

Test: Types of Convection - Question 6
Save

A finned tube hot water radiator with a fan blowing air over it is kept in rooms during winter. The major portion of the heat transfer from the radiation is due to

Detailed Solution: Question 6

Convection is a process in which thermal energy is transferred between solid and fluid flowing through it.

Test: Types of Convection - Question 7
Save

A body cooling from 80 degree Celsius to 70 degree Celsius takes 10 minutes when left exposed to environmental conditions. If the body is to cool further from 70 degree Celsius to 60 degree Celsius under the same external conditions, it will take

Detailed Solution: Question 7

Q = h A (t b – t a). Apparently the cooling depends upon the same temperature difference.

Test: Types of Convection - Question 8
Save

On a summer day, a scooter rider feels more comfortable while on the move than while at a stop light because

Detailed Solution: Question 8

The situation corresponds to forced convection when the scooter is in motion and the convective heat transfer coefficient for forced convection is greater than that for free convection.

Test: Types of Convection - Question 9
Save

What is the value of convective coefficient of oil in case of forced convection?

Detailed Solution: Question 9

In forced convection, the flow of fluid is caused by a pump, fan or by atmospheric winds. Convection mechanism involving phase changes leads to the important fields of boiling and condensation.

Test: Types of Convection - Question 10
Save

A sphere, a cube and a thin circular plate, all made of the same material and having the same mass are initially heated to the temperature of 250 degree Celsius. When left in air at room temperature, what will be their response to cooling?

Detailed Solution: Question 10

Q = h A (T – t). Here cooling depends upon the surface area of the body.
