# Answer to Question #130094 in Mechanics | Relativity for Ariyo Emmanuel

Question #130094
A manometer is used to measure the
pressure in a tank. The fluid used has a
specific gravity of 0.85, and the
manometer column height is 55 cm, as
shown in the Fig. If the local atmospheric
pressure is 96 kPa, determine the
absolute pressure within the tank?

Solution

Given data in question

Specific gravity ="0.85"

density of fluid

("\\rho) =0.85\\times1000=850Kg\/m^3"

atmospheric pressure "(P_{atm}) =96\\times10^3Pa"

Height of fluid in Manometer

"(h) =0.55m"

Therefore Pressure in the tank can be given by

"P=P_{atm}+\\rho gh"

"P=96\\times10^3+850\\times9.81\\times0.55"

"P=96\\times10^3+4.58\\times10^3"

"\\fcolorbox{red}{yellow}{$P=100.58KPa$}"

Therefore absolute pressure on the tank is 100.58KPa .
