Given :-

A manometer containing oil (rho=850kg/m3) is attached to a tank filled with air. If the oil-level difference between the two columns is 45cm and the atmospheric pressure is 98kPa,

To Find :-Absolute pressureSolution :-

converting m into cm

100 cm = 1 m

45 cm = 45/100 = 0.45 m

At first finding pgh

pgh = (850 × 10 × 0.45)

pgh = 3825

Now

Pressure = Pₐ + pgh

Pressure = 98000 + 3825

Pressure = 101825 pascal
