An inverted U-tube manometer is used to measure the pressure difference between two pipes A and B, as shown in the figure. Pipe A is carrying oil (specific gravity = 0.8) and pipe B is carrying water. The densities of air and water are 1.16 kg/m3, respectively. The pressure difference between pipes A and B is kPa.




Acceleration due to gravity g = 10 m/s2.

Correct answer is '-2.2'. Can you explain this answer?

Density of oil ρoil = 800 kg/m3
Density of water ρwater = 1000 kg/m3
Density of air ρair = 1.16 kg/m3
Acceleration due to gravity g = 10 m/s2
PA – ρoil g (0.2) – ρair g (0.08) + ρwater
g (0.38) = PB
∴ PB – PA = 2.199 kPa
Hence, the correct answer is –2.2 kPa.
