An inverted differential manometer containing an oil of sp. gravity 0.9 is connected to find the difference of pressures at two points of a pipe containing water. If the manometer reading is 400 mm, find the difference of pressures​

Answer:

pressures is 3531.6 pa at two points of a pipe containing water

Explanation:

As we know that pressure is measured with the help of height difference in manometer

So the pressure is given as

P = \rho g hP=ρgh

here we know

\rho = 0.9 \times 10^3ρ=0.9×10

3

\rho = 900 kg/m^3ρ=900kg/m

3

g = 9.81 m/s^2g=9.81m/s

2

h = 40 cmh=40cm

now by above formula

P = 900(9.81)(0.40)P=900(9.81)(0.40)

P = 3531.6 paP=3531.6pa
