An airflow at Mach 0.6 passes through a channel with a cross-sectional area of 50 cm?. The static pressure in the airstream is 50 kPa; the static temperature is 298 K. (a) Calculate the mass-flow rate through the channel. (b) What percent of reduction in area would be necessary to increase the flow Mach number to 0.8? to 1.0? (c) What would happen if the area were reduced more than necessary to reach Mach 1?

Transcribed Image Text:3.5 An airflow at Mach 0.6 passes through a channel with a cross-sectional area of 50 cm?. The
static pressure in the airstream is 50 kPa; the static temperature is 298 K.
(a) Calculate the mass-flow rate through the channel.
(b) What percent of reduction in area would be necessary to increase the flow Mach
number to 0.8? to 1.0?
(c) What would happen if the area were reduced more than necessary to reach Mach 1?
Transcribed Image Text:In part c you're asked what would happen if the area were reduced more
than necessary to reach Mach 1? If you actually did this, if you reduced
the cross-sectional area to an extremely small "pin hole" size, what would
the Mach number be through the "pin hole"?
