probe_eff {AeroSampleR} | R Documentation |
Probe efficiency
Description
In order to run this function, first produce a particle distribution with the 'particle_dist' function, then produce a parameter set with the 'set_params' function. Both of these results must be stored as per examples described in the help set with each.
Usage
probe_eff(df, params, orient = "u", method = "blunt pipe")
Arguments
df |
is the particle data set (data frame) established with the 'particle_dist' function |
params |
is the parameter data set for parameters that are not particle size-dependent |
orient |
orientation of the probe. Options are 'u' for up, 'd' for down, and 'h' for horizontal |
method |
is the model for the probe efficiency. Default is 'blunt pipe', based on Su WC and Vincent JH, Towards a general semi-empirical model for the aspiration efficiencies of aerosol samplers in perfectly calm air, Aerosol Science 35 (2004) 1119-1134 |
Value
data frame containing original particle distribution with added data for this element
Examples
df <- particle_dist() # set up particle distribution
params <- set_params_1("D_tube" = 2.54, "Q_lpm" = 100,
"T_C" = 25, "P_kPa" = 101.325) #example system parameters
df <- set_params_2(df, params) #particle size-dependent parameters
df <- probe_eff(df, params, orient = 'u') #probe orientation - draws upward
head(df)
