Question

Assume that the same person described in Problem 21.9 luckily
survives the charcoal grilling incident, but the next week his oil
furnace flue unluckily springs a leak, and starts leaking CO
into the apartment at a rate of 25 g/min. Recall that the ventilation
rate is only 0. 75 ach. Luckily, after the grill incident, he
bought a CO alarm system. Unluckily, he forgot to set the audible
alarm to "On," so he stays asleep. Luckily, the alarm still
sends a silent alarm signal to the fire department, and they
arrive 45 minutes after the leak started. They break open the
windows and rescue the (lucky/unlucky) person. Create a
spreadsheet to plot the concentration of CO in the apartment as
a function of time for the first 45 minutes after the start of the
leak. Continue the plot for the next 45 minutes, assuming that
when the firemen arrive and break open the windows, the
apartment ventilation rate jumps up to 2.5 ach. Also, they turn
off the oil heater
