A10 cm x 10 cm circuit board dissipating 10 w of power uniformly is cooled by air, which approaches the circuit board at 15°c with a velocity of 4 m/s. disregarding any heat transfer from the back surface of the board, determine the surface temperature of the electronic components at the end of the board. determine the surface temperature of the electronic components (a) at the leading edge and (b) at the end of the board. assume the flow to be turbulent since the electronic components are expected to act as turbulators. assume a film temperature of 27°c.

i lost in getting someone back.

i learned that people are really two-faced and no matter how angelic someone appears they always have a devil side and that you cant trust anyone anymore no matter how dear they are to you.

if your wondering who it waz it waz mah still miss her tho
