Question

Determine the absolute pressure in the tank if the column height of the manometer is 55

cm. The local atmospheric pressure of the tank is 100 kPa and the fluid used for the

manometer is water.

Answer 1

Absolute pressure = $\rho g h$ + ATM. Pressure

Density of water= 1000kg/m$^3$

Height= 0.55m

g= 9.81

= 100 kPa+ (1000×9.81× 0.55)

=100,000Pa+5395.5Pa= 105,395.5 Pa
