pipette_sample_depth: Compute sampling depth for pipette analysis

In evanmascitti/soiltestr: Functions for Laboratory Soil Testing

Compute sampling depth for pipette analysis

Description

Ideally, the same protocol is followed each and every time. In reality, schedules sometimes must be adjusted. This function computes the proper pipette sampling depth for a given time interval after stirring was completed.

Usage

pipette_sample_depth(
  particle_diameter,
  duration_hr,
  Gs = 2.7,
  ambient_temp_c = 22
)

Arguments

particle_diameter	equivalent spherical diameter, microns
duration_hr	hours since stirring (decimal)
Gs	specific gravity of soil particles; defaults to 2.7
ambient_temp_c	measured temperature to nearest 0.1 degree C

Value

numeric vector of length 1 (centimeters below liquid surface to sample)

Examples

pipette_sample_depth(particle_diameter = 2, duration_hr = 4)
