WebNov 28, 2024 · The sensible heat equation is as follows: Qs = k * CFM * delta T. Where: Qs is the sensible load in btuh. k is the density-specific heat product. CFM is the airflow. … Webcommonly used is the Hazen-Williams equation: Q = 0.28 x C x D. 2.63. x S. 0.54. Where Q = flow rate in m. 3 /s in SI metric or gpm in U. S. 0.28 = constant which can be used for both SI units and U.S. units with suffi- cient accuracy. C = pipe roughness coefficient (dimensionless) can be found in tables based on pipe material such as Table 1.
