determine the effect the power lost as kinetic energy in the air leaving the of fin pitch, width, and Reynolds Number on the power required. Air temperature.—The temperature of the air affects its specific weight and viscosity. The effect of varia- tion in specific weight on power has been shown.… … Pt, horsepower per inch of cylinder length -Variation of average wall heat-transfer coefficient with power, P». FiGrRE 13. Specific weight of the air, 0.0717 pound per cubic foot. RELATION BETWEEN HEAT DISSIPATION AND BLOWER POWER The wall heat-transfer coefhcient V is shown plotted against the…
