H1- COOLING TOWER [10 p] 1. What is the wet bulb temperature? How can you measure it? Is the wet-bulb temperature greater than dry-bulb temperature? Why? [10 p] 2. A cooling tower is to be designed to cool 8 kg/s of water from 37°C to 29 °C. Entering air is 25 °C and at 30 % relative humidity. Leaving air is 22 °C and at 90% relative humidity. a) Calculate the air flow rate, G. b) Determine the possible lowest...
blem 4 (20 pts) A square chip that is 12.7mm on a side has a maximum allowable chip operating temperature -75°C. To dissipate heat produced in the chip, a 4 x 4 array of copper (k-400 W/m.K) pin fins is proposed to be etallurgically joined to the outer surface of the chip. The convection coefficient is h-250 W/m'K and ambient air mperature isTo-20°C. The pin fin dimeter is D,-1.5mm and length is L,-16mm. Assuming steady-state uniform chip temperature Te-75°C and...
