Estimate the aerosol emission rate per hours
aerosol_emission(
emission_breathing = 0.06,
emission_speaking = 0.6,
speaking_ratio = 0.1,
resp_rate = 10
)
a double, emission while breathing cm^3
a double, emission while speaking cm^3
a double, between 0 and 1 for ratio between speaking and breathing
a double, the respiratory rate in liters per minute
