velocity.fpm: Calculate Air Velocity in fpm

Description Usage Arguments Examples

View source: R/rEHS.R

Description

Airflow velocity is used to capture contaminants and overcome cross-drafts, transportation of contaminants through the duct, and balancing of “losses” in the system and in the discharge of the contaminant from the stack. This is described as the “magnitude” of the system, which is a function of the velocity pressure.

Usage

1
velocity.fpm(velocity.pressure.as.h2o)

Arguments

velocity.pressure.as.h2o

pressure in the direction of flow necessary to caus the air at rest to flow at a given velocity

Examples

1
2
3
## velocity pressure of 0.2″
## velocity.fpm(.20)
## "Velocity is 1791.09 fpm"
