Pressure loss coefficients were measured for several straight body flat oval tees and laterals. For diverging flows a power law model was used to correlate branch loss coefficients as a function of branch-to-common area and flow rate ratio. The corresponding main loss coefficients for tees and laterals were -0.167 and -0.216, respectively. For converging flows a logarithmic model was used to correlate branch and main loss coefficients as functions of branch-to-common and main-to-common flow rate ratio, respectively, and pertinent geometry characteristics of the fitting. In every instance the tests were performed in accordance with ASHRAE Standard 120-2008.
