To condition the air in an office building in the winter, 1000 cubic meter of moist air per hour at 101 kPa and 22 Celsius with a dew point of 11 Celsius enter the system. The air leaves the system at 98 kPa with a dew point of 58°C. How many kilograms water vapor are added to each kilogram of wet air entering the process?
You are using a thin layer of epoxy to bond a Silicon chip to a pure aluminum plate that acts as a heat sink (epoxy layer 0.0200mm). The Silicon chip (k = 149.0 W/(m-K) is 0.200 mm thick, and has dimensions of 25.0mm by 25.0mm. The pure aluminum plate is 0.850cm thick, and has the same dimensions as the Silicon chip. The hot side of the silicon chip is measured to be 62.0°C; the cold side of the pure aluminum plate is measured to be 31.0°C. Assuming steady-state conduction (with the thin layer of epoxy acting as contact resistance, see Table 3.2.) determine the heat transfer rate through the chip. Do not add in an addition resistance due to the thickness of the epoxy layer, this has been incorporated into the contact resistance.
I'm confused about this problem. What equation would I use?
A 60,000 L fuel tank is filled with gasoline on a -10°C day, then rolled into a storage shed where the temperature is 20°C. If the tank is not vented, what minimum volume needs to be left empty at filling time so that the tank doesn’t rupture as it warms?
