[TRNSYS-users] inconsistency in flow rate units

Changing the units of an input in a proforma does not create an 
automatic conversion. The model requires that the flow rate inputs be 
given in kg/h. If your upstream component is outputting a flowrate it 
kg/s then you will need to put an equation in between it and the Type534 
in order to manually convert the value.

kind regards,

  David
