Hello,

There's this basic problem in thermodynamics that I'm stuck on. The question is

Fluid 'A' is water and 'B' is mercury. Determind the value of 'h' if the pressure at 'X' is 138 kN/m2 and 'a' is 1.5m

rhow = 1000 kg/m3

rhom = 13600 kg/m3

The main equation used is:

Absolute pressure = Gauge pressure + atmospheric pressure

Gauge pressure = rho * g * h

The value that you're supposed to get is 1.145m. Please help, I'm stuck on it for hours now and i'm sure its somethin basic that i've forgotten.

Here's a figure that might help with the problem:
