Forced air at T25C and V10 m/s is used to coolelectronic
Chapter 6, Problem 6.39(choose chapter or problem)
Forced air at T??25C and V?10 m/s is used to coolelectronic elements on a circuit board. One such ele- ment is a chip, 4 mm?4 mm, located 120 mm fromthe leading edge of the board. Experiments haverevealed that flow over the board is disturbed by theelements and that convection heat transfer is correlatedby an expression of the formEstimate the surface temperature of the chip if it is dis-sipating 30 mW
