Consider a manometer with a glass bulb (Pgas=88kPa) at one end and which is open to the atmosphere (P =101 kPa) at the other. The manometer has two liquids oil and water in it, as shown. If the oil has a density of 823 kg/m3 and water a density of 1.00x10^3 kg/m3 find the height of the water.

2. Relevant equations

P=pgh

3. The attempt at a solution

I keep deducing the equation to be;

Patm + ρwater*g*H = Pgas + ρoil*g*0.699m

Solving for H, I get 0.750m. The answer though, is 0.269m.

Where am I going wrong?
