Question regarding victor meyer method

[unholy031]

1. Homework Statement
I have this equation used for our experiment, which was Weiser's modification of the Victor Meyer method. Can someone help me understand this equation?

Vs = standard volume
V= experimental volume
t = room temp
P= barometric pressure
h=height of water meniscus
w=vapor pressure of water at the specified room temp




3. The Attempt at a Solution
1) why take the ratio of the triple point of water (or melting point?) to the room temperature?

2) i understand that the correction for barometric pressure is given by the third multiplier. why h/13.6, what is this quantity?? 13.6 is the specific gravity of mercury, btw

Hard to say anything seeing just a tiny fraction of the formula.

Temperature ratio is there to convert t to kind of an absolute scale.
