Compute all parts of following question:
Question: A manometer containing an oil with a specific gravity (SG) of 0.92 is connected across an orifice plate in a horizontal pipeline carrying seawater (SG = 1.1).
Part I: If the manometer reading is 16.8, what is the pressure drop across the orifice in psi?
Part II: What is it in inches of water?
I need help to find the pressure drop across the orifice in psi.
