Question 1:
I have a question on Quest 1. It asks for the Total Airflow Rate, when it is talking about Qv + Qr = Qe + Qr; I am kind of confused. I understand that Qv = Qe, but I'm not sure what I'm supposed to be calculating for this, the value of Qr? and what is the significance of the 7,200? I read the instructions, but I still don't understand.
Response:
The problem instructions state “Consider a system with a total volumetric flow of (Qv + Qr) = (Qe + Qr) = 7,200 m3/h.”
The 7,200 m3/h is therefore a constant which is given to you, which in turn allows you, in other parts of the assignment, to calculate Qv.
Question 2:
I also am confused about the part directly after this where it asks to perform one sample calculation for a Qv = Qe = 800 m3/h, what exactly are you asking for here?
Response:
You are being asked to calculate the items that follow on that page, the ozone and CO2 concentrations as well as the intermediate numbers for that specific value of Qv. In Q3 you’re asked to make the same calculation for a variety of ventilation rates.
Qv = Qe so is this what should be input for question 1?
ReplyDeleteThe airflow amounts for question-1 are indeed given in this question and the overall lab instructions. There isn't supposed to be anything tricky about this question.
