heres a revision question......stupid 1 though...

ooh i forgot depth of cap is L area of crossection A....... thermal conductivity is k ...... and hot oil has ∞ heat capacity...................and cap remains at constant temperature ...

ASHISH U MUSTA SEEN THIS 1 IN THE 550 PAGES U BROUSED THRU IN THAT PLACE [6]........

@shraman... i never said i browsed thru all that 550 pages.... anyway im giving it a try...

a=e=0.8
now power lost by cap = eσA(T⁴ - T₀⁴)
power absorbed by body = a.total power supplied to body...
= a.KA.ΔT/L

now, if cap remains at same temp.
power radiated = power absorbed....
==> eσA(500⁴ - 300⁴) = a.KA(T-500)/L

solve the equation.
==> T = [σL(500⁴-300⁴/K] +500

is it correct shraman?

ppl post sum questions in thermo .... all empty .......... i was forced to post a stupid q like this to fill it up ....[3]........................
