A desktop computer is to be cooled by a fan. The electronic components of the computerconsume 60 W of power under full load conditions. The computer is to operate inenvironments at temp. up to 45° C and at elevations up to 3400 m where the averageatmospheric pressure is 66.63 KPa, air density at this condition 0.73 kg/m³. The exit temp. ofair is not to exceed 60° C, air density of 0.7 kg/m³, to meet reliability requirements. Also theaverage velocity of the air is not to exceed 110 m/min at the exit of the computer case wherethe fan is installed to keep the noise level down. Assume that there is an increase in internalenergy of 10.779 kj/kg. Determine the flow rate of the fan that needs to be installed and thediameter of the casing of the fan.
The compressed air requirements of a textile factory are met by a large compressor that draws in 0.6 m3/s air at atmospheric conditions of 20°C and 1 bar (100 kPa) and consumes 300 kW electric power when operating. Air is compressed to a gage pressure of 8 bar (absolute pressure of 900 kPa), and compressed air is transported to the production area through a 15-cm-internal-diameter, 83-m-long, plastic (smooth) pipes with a surface roughness of 0.15 mm. The average temperature of compressed air in the pipe is 60°C. The compressed air line has 8 elbows with a loss coefficient of 0.6 each. In order to reduce the head losses in the piping and thus the power wasted, someone suggests doubling the diameter of the 83-m-long compressed air pipes. Calculating the reduction in wasted power, and determine if this is a worthwhile idea. Considering the cost of replacement, does this proposal make sense to you?
