Save

The temperature distribution for a plane wall, for steady state heat flow and constant value of thermal conductivity is

Test: One-Dimensional Steady-State Conduction - 2 - Question 2
Save

The temperature distribution for a hollow cylinder for steady state heat flow and constant value of thermal conductivity is

Detailed Solution: Question 2

Since heat transfer in hollow cylinder is given by 

Hence heat transfer profile is logarithmic.

Test: One-Dimensional Steady-State Conduction - 2 - Question 3
Save

The temperature distribution for a sphere for steady state heat flow and constant value of thermal conductivity is

Detailed Solution: Question 3


Hence profile will be hyperbolic.

Test: One-Dimensional Steady-State Conduction - 2 - Question 4
Save

The heat transfer in the hollow cylinder is taking place by conduction and in this case logarithmic mean temperature difference Alm is given by

Detailed Solution: Question 4

Heat transfer by conduction through hollow cylinder is given by

Also, 


Test: One-Dimensional Steady-State Conduction - 2 - Question 5
Save

What will be geometric radius of heat transfer for a hollow sphere of inner and outer radii r1 and r2?

Detailed Solution: Question 5

Heat transfer by conduction through sphere is given by

Geometric mean Area

Geometric mean radius

Test: One-Dimensional Steady-State Conduction - 2 - Question 6
Save

Thermal diffusivity is given by

Detailed Solution: Question 6

Thermal diffusivity is the ratio of thermal conductivity and thermal diffusivity

Test: One-Dimensional Steady-State Conduction - 2 - Question 7
Save

A composite slab has two layers of different materials with thermal conductivity k1 and k2. In each layer had the same thickness, the, equivalent thermal conductivity of the slab would be

Detailed Solution: Question 7

Test: One-Dimensional Steady-State Conduction - 2 - Question 8
Save

A steam pipe is covered with two layers of insulating materials, with the better insulating material forming the outer part. If the two layers are interchanged, the heat conducted

Detailed Solution: Question 8


k1 < k2 [k1 better insulator] 

Q ∝ k. This means that the material having better insulating materia! should be inside to minimize the heat flux hence if better insulating materia! is placed inside, it will reduce the heat transfer.

Test: One-Dimensional Steady-State Conduction - 2 - Question 9
Save

In a long cylindrical rod of radius R and a surface heat flux of q0 the uniform generation rate is

Detailed Solution: Question 9


Test: One-Dimensional Steady-State Conduction - 2 - Question 10
Save

The critical thickness of insulation for cylinder is given by
