Answer:
a) The flow rate of the air is 0.0104 kg/s
b) The fraction of the temperature is 23.91%
Explanation:
a) Given:
N = Number of PCBs = 8
Q = heat dissipated = 10 W
W = power supplied = -25 W
ΔT = rise temperature = 10°C
The total amount of heat dissipated is equal to:
The expression of conservation of energy is:
Replacing:
