Question

A converging nozzle with an exit area of 2.5 cm 2 is used to discharge air from a reservoir to the atmosphere (101 kPa). If the air in the reservoir is at 350 K, determine the mass flow rate for reservoir pressures of 120 kPa, 140 kPa, 200 kPa, and 1 MPa. For each case, what is the mass flow if the back pressure is reduced from 101 kPa to 0 kPa? For which of the four cases did the mass flow rate change?

Step 1

** - Exit area of the nozzle, \( A_e = 2.5 \, \text{cm}^2 = 2.5 \times 10^{-4} \, \text{m}^2 \) - Atmospheric pressure, \( P_b = 101 \, \text{kPa} \) - Reservoir temperature, \( T_0 = 350 \, \text{K} \) - Reservoir pressures, \( P_0 = 120 \, \text{kPa}, 140 \, Show more…
