I need the answer as soon as possible
A proposed method for cooling high
power density devices involves pumping
coolant through micro channels etched
in a sink. To explore the feasibility of
this concept, model the sink as a porous
disk of radius r, and thickness 8
having a volumetric energy generation
q". Coolant enters the disk at a flow
rate m and temperature T. Assume
5.3
that the outlet surface is insulated.
Determine the steady state temperature
m,T
of the insulated surface.
