E_MassTransfer: Lake evaporation (Mass Transfer method)
In jmerc13/LakeIsodrology: Lake isotope hydrology

E_MassTransfer estimates a daily rate of evaporation, E (mm/day), using a Dalton-type approach.

1	E_MassTransfer(U, els, ea, N, conv = 10)

`U`	Windspeed 2 m above the lake surface, U (m s^{-1}).
`els`	Saturated vapor pressure at the lake surface, e_{ls} (kPa).
`ea`	Atmospheric vapor pressure, e_{a} (kPa).
`N`	Empirical parameter, no standard value.
`conv`	A multiplier that converts base units to mm/day. It is assumed to be 10, but will need to be adjust for alternative units.

Evaporation as determined by (Harbeck et al. 1958, Rosenberry et al. 2007):

E = (N U (e_{ls} - e_{a})) \cdot 10
