# Calculate the airflow velocity in m/sec at the entrance to the nozzle.

Continuing with the wind tunnel described in Probs. 4.49–4.53, calculate the rate of change of pressure with respect to distance at (a) the diffuser inlet, and {b) the diffuser exit Probs. 4.49 Consider a low-speed wind tunnel (see Fig. 4.15) that is a constant width of2 m throughout its length (i.e., each cross section of the tunnel is a rectangle of width 2m). The entrance and exit heights of the nozzle are 4 m and 0.5 m, respectively. The airflow velocity in the test section is 120 mph. Calculate the airflow velocity in m/sec at the entrance to the nozzle. Consider the wind tunnel and flow conditions described in Probs. 4.49–4.52. Calculate the rate of change of velocity with respect to distance at {a) the diffuser inlet, and (b) the diffuser exit Probs. 4.49 Consider a low-speed wind tunnel (see Fig. 4.15) that is a constant width of2 m throughout its length (i.e., each cross section of the tunnel is a rectangle of width 2m). The entrance and exit heights of the nozzle are 4 m and 0.5 m, respectively. The airflow velocity in the test section is 120 mph.
