3. A heat sink for computer server absorbs all the heat generated and cools down by air flow. The air flow is 15 liter/s. The density of air near the heat sink is 1.25 kg/m³. The specific heat of air at constant pressure is 1,010 and the room air is 20°C. can handle. J/kg-°C. The temperature at the heat sink is 50°C, Find the server (heat) power in Watt that the heat sink

5. a) Using the Euler whirl equation, find the power transfer between a throughput of 100kg/s of air and a rotor where impeller speed in constant at 300m/s and the change in whirl velocity of the air is 150m/s. b) If this impeller is a compressor, producing isentropic compression, find the exit pressure and temperature of air taken in at sea level standard conditions.
