any Questions? Type them here.June 30, 2021 at 8:15 pm #20609AnonymousMember
I noticed the “Heat Transfer through Walls” questions contained negative values for temperature (-27), which resulted in a negative outcome. For example, -884.187 = 0.08187 x 400 x -27. Q= – 884.187.
However, the “Heat Pump” questions also contained negative values for temperature (-13) but those answers did not result in a negative answer. For example, 21375.64 = 1111 × 1.48 × -13. Q = 21375.64.
Why does the negative apply for one and not both?June 30, 2021 at 11:34 pm #20611AnonymousMember
I also had a question for how much does the in class assignment count towards overall grade. For instance, I was present first day of class and submitted an answer for the bioswales question. However, I do not see my answer on the list. How does the program account for technical difficulties?July 2, 2021 at 3:40 pm #20699
Negative answers have meanings that will not be assessed in this class. Since you asked, a negative answer for these problems means heat is being removed from the house. Positive means heat is entering the house.
The positive/negative answers for the in class group activity are simply because my Excel formula was slightly different when I generated the wall problems and the geothermal problems. I should make them the same, all positive.July 2, 2021 at 3:43 pm #20700
The technical difficulty was that you posted your answer as a new topic, rather than as a reply to my topic. A couple of other students did as well. I deleted them to keep the number of topics small and easily readable.

You can go to the column, right click, choose numbers, then select Absolute valueJuly 8, 2021 at 12:23 pm #20916AnonymousMember
Hello Mr. Lewis,
I resubmitted my homework answers yesterday because they didn’t upload the first time due to me using commas. I just checked my grades and I do not see the updates. Please advise.

Hi was just wondering about my hw assignment. 823. #7 in the basic add/sub ft/in it has the low number subtract high number. Is that intentional or should I switch it so I don’t get a negative answer?July 19, 2021 at 9:29 pm #21345AnonymousMember
Can you confirm if my Nail Penetration Answer Form was received? 813
Also, if you can review my answers for “Missing side” #2,5,9,13. I believe there are errors there too.
