Description

An experimental program was initiated to determine the friction factor in corrugated circular spiral ducts. Pressure loss coefficients were measured for three types of mitered elbows for various aspect ratios of flat oval ducts. The tests were performed in accordance with ANSI/ASHRAE Standard 120-1999. A regression analysis was performed on the loss coefficient data. A power law correlation was proposed to correlate the flat oval elbow loss coefficient data for each type of flat oval elbow. Error in the measurement of pressure loss coefficients and in the curve-fit data was calculated in order to estimate the quality of regression analysis.
