A barometer has liquid level 10 cm above the outside level and the gas captured inside has the pressure of 0.5 atm, what is the density of liquid?
(a) 0.5 atm-s^2/m^2
(b) 1 atm-s^2/m^2
(c) 1.5 atm-s^2/m^2
(d) 2 atm-s^2/m^2
I have been asked this question by my college professor while I was bunking the class.
My question is based upon Differential Pressure Measurements in portion Temperature and Pressure of Basic Chemical Engineering
