Internal energy function (Joules)
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))
