Question

A fin of rectangular profile has a thermal conductivity of 14 W/m C, thickness of 2.0 mm, and length of 23 mm. The base of the fin is maintained at a temperature of 220 o C while the fin is exposed to a convection environment at 23 o C with h=25 W/m2 o C. Calculate heat lost per meter of fin depth for the three tip conditions. (a) Convection, (b) Adiabatic, and (c) T (x=L) = 23 o C.

Answer #1

The extent to which the tip condition affects the thermal
performance of a fin depends on the fin geometry and thermal
conductivity, as well as the convection coefficient. Consider an
alloyed aluminum (k = 180 W/m*K) rectangular fin of length L = 10
mm, thickness t = 1 mm, and width w >> t. The base
temperature of the fin is Tb = 100°C, and the fin is exposed to a
fluid of temperature T∞ = 25°C. Assuming a uniform...

For a straight, rectangular fin that is 2 cm in length, and 1 cm

Tair = 25oC, what is the heat dissipated from
the fin per meter of depth?

Consider an aluminum pin fin (k = 240 W/m·K) with a 2 mm by 2 mm
square cross-section and a length of 4 cm that is attached to a
surface at 100o C. The fin is exposed to air at 25o C with a
convection heat transfer coefficient of 20 W/m2 · o C. Determine
the rate of heat transfer and the tip temperature of the fin for
the following cases:
(a) Convection from the fin tip.
(b) Adiabatic tip...

A stainless-steel fin (k = 16 W/m. °C) has a length of
15 cm and a square cross section 12.5 by 12.5 mm attached to a wall
maintained at 250 °C. The heat-transfer coefficient is 40 W/m. °C,
and the environment temperature is 90 °C. Calculate the percentage

A certain material has a thermal conductivity of 0.90 W/(m
oC). If the area of a wall made of the material is 20
m2, the thickness of the wall is 0.6 m, and the heat
transfer through that wall by conduction is 400 W, what is the
temperature difference between the surfaces of the wall? Give your
answer in terms of oC . (Enter the number only -- do not
include the units in your answer.)

A
40-mm-thick plain wall of thermal conductivity 0.04 W/m-K and of
temperature 304 K is exposed to both cold fluid and surroundings
both at 298 K. The cold fluid and wall provide that the heat
transfer coefficient is 10.5 W/m2-K and the emissivity of the wall
is 0.83. Given that the area of the wall is 1.5m2 If the total heat
transferred is 140.6987W, find the temperature of the other side of
the plain wall

A pin fin, fabricated from an aluminum alloy (k = 185 W/m K),

A spherical tank, 1.5 m in diameter, is maintained at a
temperature of 120 ◦C and exposed to a convection environment with
heat transfer coefficient, h=15 W/m2
◦C and T∞ =20 ◦C. For the same surface
temperature of the tank, it is desired to insulate the tank in
order to decrease the heat loss by 45 percent, determine the
thickness of insulation layer (k=0.2 W/m ◦C ) and the outer surface
temperature.
