1.	What is the pressure difference across a cylinder which consists of water and has a height difference of 20m?(a) -196.2 kN/m^2(b) -1.962×10^-5 bar(c) -196.2 kN/m^2(d) -1.962×10^-5 barThis question was addressed to me during an interview.The question is from Standard Atmospheric Model topic in section Atmosphere and Air Data Measurement of Aircraft Performance
Answer» CORRECT CHOICE is (a) -196.2 kN/m^2 Easiest EXPLANATION: The ANSWER is -196.2 kN/m^2. Given Δh=20m, g=9.81m/s^2, ρ=1000kg/m^3. From ΔP=-ρg∆h, ΔP=-10009.8120 ΔP=-196200 N/m^2 or ∆P=-196.2 kN/m^2.
