Usage
tens.to.sapflow(tension, Tmax)
Arguments
tension |
Vector with tension. |
Tmax |
Vector with corresponding maximums of tension. |
Value
Return a numerical vector containing the sap flow density

Examples
Tmax = c(rep(2.5, times=5), rep(2.7, times=5), rep(3.2, times=5), rep(3.4, times=5))
tension = c(5:25)
