Question Orifice pressure drop in meters = (Pa (N/m^2 ))/(ρg (N/m^3 )) This gives answer in meters Question 1 Given: T = 312 K ρ = 1.1333 kg/m^3 (From Air properties table) g = 9.81 m/s^2 Orifice pressure drop = 470.72 Pa Calculation: Orifice pressure drop in meters =...

or do I need to use an Air properties table to find ρ at the temperature I am given?

Hi, Thank you for the reply. Still slightly confused. It is ΔP that I need to find in order to calculate the ideal mass flowrate of air. Do I already have the answer to the question, ie ΔP = 470.72 Pa ?

Homework Statement ΔP = 1000 x 9.81 x (Orifice pressure drop in m) Pressure drop across orifice = 470.72 Pa 2. Homework Equations 3. The Attempt at a Solution I am not sure how this works. How can pressure be converted to meters? It does not make sense to me. Any...
