Air enters a room at two inlets and leaves at one outlet, as shown in Fig. 4.49. Determine V3 for a steady-flow situation if the velocity Ñ´2 is
a) 10 m/s,
b) 20 m/s,
c) 30 m/s. The temperature and pressure of the air at all locations are approximately 25°C and 90 kPa, respectively. The air can be assumed to be incompressible for low velocities (below about 100 m/s).
