Re: [TRNSYS-users] viscosity conversion in type 156 reads wrong

[David BRADLEY <d.bradley@tess-inc.com>]

Nidal,

  I don't know if anyone followed up with you about this but you are correct; the conversion factor has an error in it. You can fix the issue by opening the Studio and selecting "unit dictionary" from the "tools" menu. Select "dynamic viscosity" then click on the "poise" equivalent unit. Click "edit" and change the conversion factor (and associated comments) from 1.0 to 0.1.

 Apologies for the error! A fixed version will be included with the next Trnsys update.

kind regards,

 David

Dear sir

In type 156 ( thermal storage), I found a problem in converting the viscosity when switching from kg/m.h to poise, as follows:

The correct conversion of viscosity from kg/m.h to poise is:

2.352 kg/m.h =0.00653 poise

 While in TRNSYS 18 and using type 156/ parameter 10 you will find:

2.352 kg/m.h = 0.000653 poise

Please advise.

Best Regards

Nidal Abdalla
