All adiabatic flows are reversible. True False 도 Air ( Y = 1.4, R = 287 J/kgK) is flowing through a nozzle at 390 m/s. At a particular location in the nozzle, static temperature is 299 degrees Kelvin, and the area is 1.1 m². What is the value of du/dA at this point in m/s per m²? (in other words, how much will the velocity increase/decrease for a small change in area?)
