don't degrade due to water absorption (which allows for more consistent predictions). I would not use those for the main body (PURs w/ R- value of 10 instead), but I want to know if a vacuum plate would be worth it ( cause they're ~$40 a small panel),Thanks!

It's fine...I do need you to share your test to firstname.lastname@example.org...it says I do not have access

For B it has a 5 min set up, a 30 min set or cool down time, 20 min for testing and typically there are 8 teams per period and it takes time to get the hot water to every time. That is very near the total time of each period. add in the ingress/egress of each set of teams and the supervisor has to review what is logged for each team.
Perhaps you aren't used to running this event in parallel? The typical way i recommend this event is as follows (let's assume 10 teams and 30 mins cooling time and a 50 minute time block):
0 - 5 mins: Get teams checked in, settled down
5 - 10 mins: 5 min device setup time
10 - 15 mins: in 30 second intervals, each team receives their hot water. I recommend the teams bring the beakers to the hot water source instead of the hot water being brought to the teams
15 - 20 mins: teams provide estimates, secure devices, etc
20 - 40 mins: cooling period, teams taking the test. Event supervisors go around room and insert thermometers into all the beakers
40 - 45 mins: in 30 second intervals, supervisor records temperatures for each team, teams can continue to take test if supervisor desires
45 - 50 mins: in 30 seconds intervals review results with teams / allow them to cleanup / leave
Obviously there are many variations possible, particularly the fact that most tournaments now use 60 min blocks, not 50 min blocks.
The recommendation I have is for the event supervisor to have enough thermometers to leave them in all the beakers (i.e. in the example I listed that would be 20 thermometers). Most school labs have tons of them sitting around so they aren't a big expense. That alleviates the time crunch regarding the 20 seconds wait period.

Any thoughts on why so much time is given for set up or what kind of modifications are possible based on the test conditions?
WhatScience? wrote:Hey guys...so I have been taking practice tests and have been thinking...how much of the test is actually going to be on what the rules say.(I know that in theory it is everything but in reality I doubt it will be that much). That is why I have been taking notes on everything thermo I can find since June but does anyone have a good list of topics to study?
