## Homework Statement

The fluid in a manometer tube is 40% water and 60% alcohol (specific gravity = 0.8). What is the manometer fluid height difference if a 50kPa pressure difference is applied across the two ends of manometer?

## Homework Equations

P1-P2=50 kPa

P3-P2=(ρgh)alc

P3-P1=(ρgh)h2o

then,

P2=P3-(ρgh)alc

P1=P3-(ρgh)h2o

equating

(ρgh)alc-(ρgh)h2o = 50 kPa

## The Attempt at a Solution

P1-P2=50 kPa

P3-P2=(ρgh)alc

P3-P1=(ρgh)h2o

then,

P2=P3-(ρgh)alc

P1=P3-(ρgh)h2o

equating

(ρgh)alc-(ρgh)h2o = 50 kPa

Now, i'm stuck with getting h. since i don't have any idea how to get it using my attempts.

help me please.
