vapour.df: Hydrocarbon data

Description

When petrol is pumped into a tank, hydrocarbon vapours are forced into the atmosphere. To reduce this significant source of air pollution, devices are installed to capture the vapour. A laboratory experiment was conducted in which the amount of vapour given off was measured.

Usage

data(vapour.df)

Format

A data frame with 125 observations on the following 5 variables:

t.temp

initial tank temperature (degrees F)

p.temp

temperature of the dispensed petrol (degrees F)

t.vp

initial vapour pressure in tank (psi)

p.vp

vapour pressure of the dispensed petrol (psi)

hc

emitted dispensed hydrocarbons (g)(response)

Examples

data(vapour.df)
vapour.lm<-lm(hc~ t.temp + p.temp + t.vp + p.vp, data=vapour.df)
