A gas pressure of 65,000.0 Pa (gage pressure) is applied to one leg of a U-tube manometer, which contains a fluid of density of 1905.0 kg/m3. The other leg is open to atmosphere. What is the manometer reading? Draw the U-tube manometer and label all relevant parameters. Hint: You may assume that air density is much less than the fluid density

Answer:

[tex]h=3.4817\ m[/tex]

Explanation:

Given:

  • Pressure of a gas, [tex]P=65000\ Pa[/tex]
  • density of the fluid in the manometer, [tex]\rho=1905\ kg.m^{-3}[/tex]

We know that:

[tex]P=\rho.g.h[/tex]

putting respective values

[tex]65000-101325=1905 \times 9.8\times h[/tex]

[tex]h=3.4817\ m[/tex] is the reading in terms of the fluid column height on the manometer.

Considering the rise in the level of fluid this fluid is not suitable for such huge pressures for a practically convenient manometer.
