A venturi tube mounted on an airplane has a free stream velocity V1at the inlet. The area relation between the throat and the inlet A2/A1 = 1/4. The pressure difference between the throat and the inlet is given by 𝑃1 − 𝑃2 = 80 𝑝𝑠𝑓. If the airplane is flying at standard sea level conditions, what is its velocity?
