2. Find the Mach number and air speed corresponding of 500 kPa(abs) in an air flow with a (static) pressure of 100 kPa and measured (stagnation) temperature of 500 K. DISCUSSION: Suppose that, instead of assuming that a normal shock occurs upstream of the Pitot tube, it is assumed that the flow upstream is ISENTROPIC... what would the estimated flow speed be in that case?

Air with a stagnation pressure of 1000 kPa and stagnation temperature of 500 K flows isentropically into a 100 kPA ambient (back) pressure. Calculate the Area ratio at the exit of a nozzle for isentropic flow with these conditions. Further if flow is considered isentropic within the nozzle calculate the isentropic nozzle efficiency if the area ratio at the nozzle exit were 1.2 rather than your calculated value for isentropic exit conditions above.

1. Find the loss in stagnation pressure through a normal shock with an incoming flow at a Mach number of 2 and incoming flow stagnation pressure of 200 kPa(abs). In addition to the stagnation pressure downstream of the shock, also give the Mach number and (static) pressure downstream of the shock. DISCUSSION: Compare the "shock compression" (increase in STATIC pressure) obtained from the normal shock to the compression that would be obtained from an isentropic deceleration to the same Mach...

Air at stagnation pressure of 700 kPa and temperature of 530 K enters a isentropic converging-diverging nozzle. The throat area of the nozzle is 5 cm2, the exit area is 12.5 cm2. The back pressure is 350 kPa and a normal shock occurs within a diverging section. Determine (a) exit Mach number, (b) change in stagnation pressure, (c) upstream and downstream Mach number of shock (d) cross sectional area where shock occurs (e) back pressure if the flow were isentropic...

Air flow is induced in an insulated tube of 7.16 mm diameter by a vacuum pump. Air is drawn from a room where stagnation pressure is 101 kPa (abs) and stagnation temperature 23 °C, through a smoothly contoured converging nozzle. At station (1), where the converging nozzle joins the constant area tube, the static pressure is 98.5 kPa (abs). At section (2), located some distance downstream in the constant area tube, the air temperature is 14 °C. Determine a) the...
