Rho: Gives the air density for a certain atmosphere condition.

In Bolshom/optimumtt: A colection of functions to help cyclists.

Description

By inputting temperature, dew temperature and air pressure, it's possible to calculate the air density in kg/m^3.

Usage

Rho(t, t.dew, hpa)

Arguments

t	Temperature in Celsius.
t.dew	Dew temperature in Celsius.
hpa	Air pressure in hPa.

Value

rho	Returns the air density calculation in kg/m^3.

Examples

## The function is currently defined as
function (t, t.dew, hpa)
{
    rho = ((P.d(hpa, t.dew)/(287.0531 * (t + 273.15))) + (P.v(t.dew)/(461.4964 *
        (t + 273.15))))
    return(rho)
  }

t=23.2 #celsius
t.dew=20 #celsius
hpa=1012.1 #hpa
rho=Rho(t,t.dew,hpa)
