Can a team be eliminated from the Engineering Design Event by the judges, if every document of theirs was accepted and they are present at the Engineering Design Event?

Steps:

  • calculate average time between left circle and right circle for each run
  • add any penalties to these times
  • decide on the best time of Team A and Team B
  • slowest time between these two best times is T_team
  • fastest time between these two best times gets multipled by 1.25 and is T_max
  • use formula from FSG Rules 2023 D4.4.3

20 / 20

You would like to drink a cup of very hot coffee with milk early in the morning, but you
are in a hurry and have only 5 minutes until you have to leave for work. At which time
after brewing should you add the cold milk to the coffee and stir in order to decrease the
temperature of the mixture as much as possible:
a) 0 minutes (immediately),
b) 2 minutes, or
c) 4 minutes?
Suppose that the stirring can be done instantaneously and that you need the last one
minute for drinking.

brew temperature C = 80 ◦C, temperature of milk = M = 10 ◦C, room temperature
0 = 20 ◦C, volume of coffee VC = 300 ml, volume of milk VM = 100 ml, specific heat
capacity of coffee cC = 4180 J/(kgK), specific heat capacity of milk cM = 3500 J/(kgK).

Please enter only the letter of the corresponding answer
