NAME
Physics::Psychrometry - Perl extension for calculating Psychrometric measures for moist air
SYNOPSIS
use Physics::Psychrometry;
my $db = 24.6; # C
my $rh = 0.68; # RH 0.0 to 1.0
my $p = 102; # kPa
my $e = Physics::Psychrometry::dbrh2e($db, $rh);
my $dp = Physics::Psychrometry::e2dp($e);
my $wb = Physics::Psychrometry::dbdp2wb($db, $dp, $p);
my $w = Physics::Psychrometry::e2w($e, $p);
my $h = Physics::Psychrometry::dbw2h($db, $w);
my $es = Physics::Psychrometry::t2es($db);
my $v = Physics::Psychrometry::dbw2v($db, $w, $p);
my $ws = Physics::Psychrometry::es2ws($es, $p);
my $ds = Physics::Psychrometry::rhws2ds($rh, $ws);
my $da = Physics::Psychrometry::wv2da($w, $v);
my $q = Physics::Psychrometry::w2q($w);
my $x = Physics::Psychrometry::wv2X($w, $v);DESCRIPTION
Calculates a variety of Psychrometric values for moist air Blah blah blah.
EXPORT
None by default.
METHODS
dbrh2e
Convert dry bulb (C) and Relative Humidity (0.0 to 1.0) to vapor pressure (kPa)
my $e = Physics::Psychrometry::dbrh2e($db, $rh);e2dp
Convert vapor pressure (kPa) to Dewpoint (C)
my $dp = Physics::Psychrometry::e2dp($e);dbdp2wb
Convert dry bulb (C), Dewpoint (C) and airpressure (kPa) to wet bulb (C)
my $wb = Physics::Psychrometry::dbdp2wb($db, $dp, $p);e2w
Convert vapor pressure (kPa) and airpressure (kPa) to humidity ratio
my $w = Physics::Psychrometry::e2w($e, $p);dbw2h
Convert dry bulb (C) and humidity ratio to enthalpy (kJ/kg)
my $h = Physics::Psychrometry::dbw2h($db, $w);t2es
Convert dry bulb (C) to saturated vapor pressure (kPa)
my $es = Physics::Psychrometry::t2es($db);dbw2v
Convert dry bulb (C) and humidity ratio to specific air volume (m3/kg)
my $v = Physics::Psychrometry::dbw2v($db, $w, $p);es2ws
Convert saturated vapor pressure (kPa) to saturated humidity ratio
my $ws = Physics::Psychrometry::es2ws($es, $p);rhws2ds
Convert Relative Humidity (0.0 to 1.0) and saturated humidity ratio to degree of saturation (0.0 to 1.0)
my $ds = Physics::Psychrometry::rhws2ds($rh, $ws);wv2da
Convert humidity ratio and specific air volume (m3/kg) to density of moist air (kg/m^3)
my $da = Physics::Psychrometry::wv2da($w, $v);w2q
Convert humidity ratio to specific humidity (ratio)
my $q = Physics::Psychrometry::w2q($w);wv2X
Convert humidity ratio and specific air volume (m3/kg) to absolute humidity (kg/m3)
my $x = Physics::Psychrometry::wv2X($w, $v);SEE ALSO
