Consider a droplet of methanol with an initial diameter of 80 µm. It is injected into a chamber with an ambient temperature of 750 K and ambient pressure of 1 atm. Calculate the lifetime of the droplet. An additive is reported to reduce the boiling temperature of methanol by 40 K without affecting the heat of vaporization. Unfortunately, the additive also causes the initial droplet size to increase to 95 µm. Calculate the new droplet lifetime. Describe briefly how droplet lifetime would be affected if the ambient pressure were increased to 10 atm.
