vol {biogas}

Biogas Volume from Batch Reactors

Description

Biogas volume measurements from twelve batch reactors.

Usage

data("vol")

Format

A data frame with 288 observations on the following 4 variables:

id

identification code, a unique value for each reactor in the dataset. A factor with levels 2_1, 2_2, 2_3, 2_4, 2_5, 2_6, 2_7, 2_8, 2_9, 2_10, 2_11, and 2_12

date.time

date and time of mass measurement, a POSIXct object.

days

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

vol

volume of biogas removed at date.time in mL, a numeric vector.

Details

These data are meant to be example data for multiple functions, e.g., stdVol, cumBg, or summBg. Reactors were 500 mL glass serum bottles with butyl rubber septa and screw caps. Volume was measured using syringes. Data in vol, mass, xCH4, and setup are from the same reactors.
