The Type 56 manual suggests that the specific mass flow rate be greater than 13 kg/h-m^2. Say I wanted to convert this to mass flow rate in kg/s and the fluid was flowing through a 3/8" (or 9.525 mm) inside diameter pipe. Here's what I'm doing...
13 kg/h-m^2 x (7.1256 E-5 m^2) x (h / 3600 sec) = 2.573 E-7 kg/s
This seems like an awfully low mass flow rate, since what I've seen in literature for floor heating applications is around .05 kg/s. Am I missing something here?
