Question

An ideal gas with k = 1.4 is flowing through a nozzle such that the Mach number is 1.6 where the flow area is 70 cm2. Approximating the flow as isentropic, determine the flow area at the location where the Mach number is 0.8. Use data from tables. The flow area at the location where the Mach number is 0.8 is cm2.

Answer 1

A2 = 58.12 cm^{2}[/tex]

Step-by-step explanation:

Using Area ratio for A-32 in mach table from the given mach values.

A2 = 1.038A*

=
`(1.038)/(1.250)*A1`

=
`(1.038)/(1.250)*70`

= 58.12 cm^{2}[/tex]
