If using the plunge test for measuring the RTI of sprinkler
head, the hot air temperature is (100+X)°C and the air velocity is
1.5 m/s, estimate the RTI of the sprinkler head of a red glass bulb
if its activation time is measured as 80 s. What will be the
activation time if the air velocity is changed to 1.2 m/s? Note
that the room temperature is assumed to be 20°C. X= 2
