Parallel head loss

[mfqd]

Hi,

I have a situation that i would like to have some comments about.
In some literature is mentioned the equation that is in the attachment, for the solar collector arrangement also in attached.
The solar array is parallel and the equation was generated through electrical resistance comparison.

Is this approach correct?

Can anyone give me some help.
Is the post badly explained?...

Thanks

Using the electrical analogy is valid so long as the idealizations involved are fully recognized. The actual installed system can vary quite significantly due to construction variations, scale build-up, debris in the piping, .... Elements with restricted flows may be found through scanning with non-contact temperature measuring equipment--higher temperature rise in an element would suggest a likely flow restriction.
