is used to determine the time period for a concentration buildup that will occur

1	time.interval(volume.cf, flow.rate.cfm, contaminant.generation.rate.cfm, concentration.ppm)

`volume.cf`	volume of room or enclosure (cubic feet)
`flow.rate.cfm`	flow rate of the air (cfm)
`contaminant.generation.rate.cfm`	rate of generation of contaminant (cfm)
`concentration.ppm`	concentration of the contaminant to predict (ppm)

## time.interval(75000, 2500, 1.4, 175)
## 75000 is room volume
## 2500 is air flow rate
## 1.4 cfm of contaminant generation
## "Time interval is 11.24 minutes for 175.0 ppm"
