Homework Statement
The tank shown in the figure is located in a place with a
atmospheric pressure (90 kPa abs).
If X = 3.50 m, Y = 1.80 m and the vapor pressure of the alcohol is
13 kPa (abs), determine:
1) manometer reading "A" in KPa.
2) The height "h" of mercury manometer.

The Attempt at a Solution
I have did this:
Equating P(A) = P (alcohol) + 0.035 (Salcohol) ([PLAIN]http://upload.wikimedia.org/math/3/3/4/334de1ea38b615839e4ee6b65ee1b103.pngwater )
P(A) = -76.97 kPa. (Using P(alcohol)= Palchol abs -Patm = -77 kPa)
Equating
P(A) +[PLAIN]http://upload.wikimedia.org/math/3/3/4/334de1ea38b615839e4ee6b65ee1b103.pngalc (h) +1.8 http://upload.wikimedia.org/math/3/3/4/334de1ea38b615839e4ee6b65ee1b103.png (alc) = [PLAIN]http://upload.wikimedia.org/math/3/3/4/334de1ea38b615839e4ee6b65ee1b103.png(Hg) (h)
Solving for "h"
h=0.124 m
