Discussion :: Heat Transfer
-
A 10 cm dia steam pipe, carrying steam at 180°C, is covered with an insulation (conductivity = 0.6 W/m.°C). It losses heat to the surroundings at 30°C. Assume a heat transfer co-efficient of 0.8 W/m2.°C for heat transfer from surface to the surroundings. Neglect wall resistance of the pipe and film resistance of steam. If the insulation thickness is 2 cms, the rate of heat loss from this insulated pipe will be
|
A.
greater than that for uninsulated steam pipe.
|
|
B.
less than that of the uninsulated steam pipe.
|
|
C.
equal to that of the uninsulated steam pipe.
|
|
D.
less than the steam pipe with 5 cms insulation.
