FLUID MECHANICS - CASE STUDY SOLUTION



U-Tube Differential Manometer

 

To determine the pressure difference between point A and B, start from one end and work to the other end:

     pA - ρ1gh1 - ρ2gh2 + ρ1g (h1 + h2) = pB

Rearrange terms to yield:

     pA - pB = gh22 - ρ1)

For the given values of ρ1 = 1000 kg/m3, ρ2 = 1600 kg/m3 and h2 = 0.75 m:

     pA - pB = (9.8 m/s2) (0.75 m) (1600 - 1000) kg/m3
                 = 4.4 kPa
