Question

A barometer has liquid with density 1 Kg/m^3, and the gas has pressure 0.5 atm, what is the height of liquid level?

(a) 0.01 atm-m^2-s^2/kg

(b) 0.05 atm-m^2-s^2/kg

(c) 0.1 atm-m^2-s^2/kg

(d) 0.5 atm-m^2-s^2/kg

I had been asked this question in an online interview.

Enquiry is from Differential Pressure Measurements in division Temperature and Pressure of Basic Chemical Engineering

Answer 1

The correct answer is (b) 0.05 atm-m^2-s^2/kg

Easy explanation: Pressure of gas + Pressure of Liquid = atmospheric pressure, => 0.5 atm + 1*10*h = 1 atm, => h = 0.05 atm-m^2-s^2/kg.
