strawMass {biogas}

Mass Change of Batch Reactors

Description

Mass measurements for 12 batch anaerobic reactors with ground straw as a substrate.

Usage

data("mass")

Format

A data frame with 89 observations on the following 4 variables.

bottle

identification code, a unique value for each reactor in the dataset. Integer with all values from 1 to 12.

date.time

date and time of mass measurement, a POSIXct object.

time

elapsed time of mass measurements (from reactor setup) in days, a numeric vector.

mass

total reactor mass in g, a numeric vector.

Details

These data are meant to be example data for mass2vol or cumBg, for gravimetric determination of biogas production. Reactors were ca. 600 mL glass serum bottles with butyl rubber septa and screw caps. Masses were measured with an electronic balance to 10 mg. Data in strawPressure, strawSetup, and strawComp are from the same reactors.
