Question

In the sketch, the height h is equivalent to 150 kPa and the barometer reading is 100 kPa. What is pressure inside the tank that is attached to the manometer?

(a) 250 kPa

(b) 150 kPa

(c) 100 kPa

(d) 50 kPa

I had been asked this question in an online interview.

Question is taken from Pressure and Hydrostatic Head-II topic in division Introductory Concepts of Chemical Process Calculation

Answer 1

Right choice is (a) 250 kPa

For explanation I would say: Pressure inside the tank = atmospheric pressure + pressure due to liquid height h.
