Computes the Equivalent Narcotic Depth for a Trimix mixture at given depth.
END(depth, g)Numeric value or vector giving the Equivalent Narcotic Depth
in metres for each value of depth.
depth of dive, in metres. A numeric value or a vector of values.
The breathing gas. An object of class "gas".
This function does not check whether the breathing gas would be safe (it could be hypoxic or toxic at the depth in question). It is not applicable to altitude dives.

Applies the standard formula for equivalent narcotic depth:
the depth at which compressed air would have the same
partial pressure of narcotic gases as the specified gas g
at the specified depth
(assuming that both Nitrogen and Oxygen are narcotic).

# Trimix 18/50
# (18% oxygen, 50% helium)
END(30, trimix(0.18, 0.5))
