ATM 348 Home Project #1 Specifications

(Please Check Notes for Details)

(To simplify your calculation, I now only request the CASE #1 calculation, in which the cloud droplet temperature is kept the same as that of the environmental air)

Constants

Rw   = 461.0  J/kg/K
rhow = 1000.0 ;kg/m3
sigma = 0.075  N/m2
mw  = 18.0  g/mol
ms  = 58.5  g/mol
M  = 1.0e-14  g
ion  = 2.0
D  = 2.5e-6  m2/s
lamda = D
L   = 2.5E6  J/kg

 Environmental condition (temperature and relative humidity)

TF   = 273.16  K
RHF   = 1.05

 
Initial condition

R0  = 1.0  micrometer
T00  = T

Integration

Use N  = 3601 steps with time interval deltaT = 2  seconds to integrate the condensational growth model  for two hours.

Requirement
Please hand in your procedure, the program, printout of the radius every 5 minutes, and graph of the radius as a function of time.
