Sorry, don't understand your question.

You state that you are a Refrigeration Designer and yet you are asking about basic things.

Refer to your text books.

Yeah, but in country Earth, you can expect all kind of peoples :p

And for every ft or mtr how much loss are gone in the capacity of the compressor there's no loss gone in the compressor.
You have to calculate DP over the lines and translate this to your compr. cap.

hi guys,

sorry for misleading question. actually i ones read from this site that your cooling capacity changes per 2F pipe loss = 100%, 4 F = 90 % and soon on or maybe i'm wrong thats why i want to read it again but can't seem to find it in the forum. i think its from dupont.

i just need some technical details for customer presentation. because right now we will be installing a 70 mtr vertical rise. and the allowable for compressor is 50 mtr with PTrap every 3 to 4 mtr. just need to gather more info.
