HVAC/IAQ lab formula

Hi everyone,

Two comments:
1) We got a question from a student and am posting the response here in case others are having the same problem:

Q:  In the Week Four HVAC/IAQ Lab Instructions, the equation for energy carried by airflow only shows up as
Eairflow=m×[]
when I download it.

A: The formula for Eairflow is m*[0.24T+W(0.45T+1061)]

Where m should be m with a dot over it as the mass flow rate, T is the temperature, and W is the relative humidity as described in the parameters of question 2 of the Excel file.

2) EDITED: I had a previous comment here before which was incorrect, sorry!
