[TRNSYS-users] Storage tank - input inconsistency when 10min interval

[David BRADLEY]

Michal,
   There may not really be a problem here. TRNSYS outputs are averages 
over each timestep and inputs are assumed to be constant over a 
timestep. As a result the inputs to Type534 are assumed to be the 
average flow rate over your 10 minute period. Type9 also gives you 
various options for what kind of data you are giving it (averages over 
the timestep, instantaneous values at the end of the timestep, etc.). If 
you have integrated flows over the 10 minute periods, you can use an 
equation to back out what the average flow rate was over the period.
Kind regards,
  David
