A nоzzle duct is plаced in а rооm аt standard conditions. Some of the exit conditions are known: = 0.24, = 280 K, and = 1 m2. A differential pressure gauge -as shown- is measuring the difference in pressure between the inlet and exit to be 3.721 kPa. Find: (a) The inlet’s cross-sectional area. Answer: [A1] m2 (round to one decimal place) (b) The Mach number at the inlet. Answer: [M1] (round to two decimal places)
