square integrated chips ics 1 cm by 1 cm mounted on flat mothcrboard cannot havc surfacc tempcra

So here we're giving a couple of data. We're told that the area of the circuit board is 12 by 18

So we start from the general formula for the convection heart rate. So Q -convect equals K -conv

we will be calculating the maximum allowable power and maximum allowable power from here it can

So here in this fashion the maximum rate at which the heat can be dissipated in the chip when th

Here it is given that the value of Q1 minus Q2 minus Q3 is equal to the 0, where the value of P,

Question

Square integrated chips (ICs), 1 cm by 1 cm, mounted on a flat motherboard cannot have surface temperature exceeding 70Â°C. You may assume uniform surface temperature. If 33Â°C air blows over the motherboard at 10 m/s to cool the ICs, what is the maximum heat generation of the second IC, with a center-point 8 cm from the leading edge? [10] If for the same air speed, we use a device at the leading edge to guarantee a totally turbulent boundary layer, what is the second IC's maximum heat generation?
