Avery long aluminum f in (k -180 w/m. k) with cross sectional area of a 5 mm2 is to a surface at temperature of 60 °c and is subjected to convection heat transfer with h- 35 wm2.k and t. 25 °c. if the perimeter of the fin is p 8 mm, find the point along the fin /rm for which 0/0o 0.01.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.

For a gate width of 2 m into the paper, determine the force required to hold the gate abc at its location.
