Question

An open tank 10 m deep is completely filled with a liquid of density 5 kg/m^3, what is the pressure difference at the top and bottom?

(a) 100 N/m^2

(b) 250 N/m^2

(c) 500 N/m^2

(d) 1000 N/m^2

This question was addressed to me by my college professor while I was bunking the class.

The question is from Measurement of Pressure in division Temperature and Pressure of Basic Chemical Engineering

Answer 1

Correct choice is (c) 500 N/m^2

The explanation: Pressure difference = dgh = 5*10*10 = 500 N/m^2.
