internal.energy: Internal energy function (Joules)

In rLakeAnalyzer: Lake Physics Tools

Description

Calculates the internal energy of the water column with temperature and hypsography

Internal energy is the thermal energy in the water column, which is calculated by multiplying the specific heat of water (J kg-1 K-1) by the temperature and mass of the water in the lake.

Usage

internal.energy(wtr, depths, bthA, bthD)

Arguments

wtr	a numeric vector of water temperature in degrees C
depths	a numeric vector corresponding to the depths (in m) of the wtr measurements
bthA	a numeric vector of cross sectional areas (m^2) corresponding to bthD depths
bthD	a numeric vector of depths (m) which correspond to areal measures in bthA

Value

internal energy in Joules m-2. (Currently not vectorized..)

Examples

bthA  <-	c(1000,900,864,820,200,10)
bthD	<-	c(0,2.3,2.5,4.2,5.8,7)

wtr	<-	c(28,27,26.4,26,25.4,24,23.3)
depths	<-	c(0,1,2,3,4,5,6)

cat('Internal Energy for input is: ')
cat(internal.energy(wtr, depths, bthA, bthD))
