Air mass flow rate equation in ZoneHVAC:Baseboard:RadiantConvective:Water

Hi all,

The ZoneHVAC:Baseboard:RadiantConvective:Water model calculates a UA value using the log mean temperature difference (LMTD) method for heat exchangers. In this calculation, the air mass flow rate is obtained from the following linear equation: m_dot = 0.0062 + 2.75e-05*q, where the air mass flow rate varies as heating capacity of the baseboard heaters varies. This linear equation was added by Daeho Kang in 2010: Github Issue 2858

Does anyone know where I can find information about the values of the constant and the coefficient? I have looked into the documentation and at Github, but besides the equation itself, there is little information.

Thanks!
