- Q.3. Airflow at M1 = 2.2 takes a compression turn of 12° and then another turn of angle as shown in the figure. What is the maximum value of 0max for the second shock to be attached? 3 M1 = 2.2 Omax (2 12°arrow_forwardI need the answer quicklyarrow_forwardConsider an oblique shock generated at a compression corner with adeflection angle θ = 18.2◦. A straight horizontal wall is present above thecorner, as shown . If the upstream flow has the propertiesM1 = 3.2, p1 = 1 atm and T1 = 520◦R, calculate M3, p3, and T3 behindthe reflected shock from the upper wall. Also, obtain the angle whichthe reflected shock makes with the upper wall.arrow_forward
- In the figure below, M1 = 3.0 and A1 = 2.0ft?. If the fluid is carbon monoxide and the shock occurs at an area of 1.8ft?, what is the minimum area possible for section 4?

A turbojet aircraft flying at speed of 1645 km/h and altitude of 9000 m. A supersonic intake was designed with a conical center body, which generated one oblique shock wave and normal shock wave at the inlet of the aircraft. The deflection of the conical center body is a 10°. Calculate the fluid flow properties and velocity at the aircraft inlet of the intake. Assume a weak solution. Take: R= 0.287 kJ/kg K, and Cp=0.9 kJ/kg K.arrow_forward

A charge of air at 100kPa and 20C is taken into the cylinder and compressed adiabatically y=1.4. After combustion at constant pressure the temperature is 1090°C. The expansion which follows is adiabatic.

Wind (air having a density p=1,2 kg/m3 ) at a free-sream speed of 3 m/s with an atmospheric pressure of 100 kPa far upstream the structure blows over the structure. The air entrance to the structure is at ground level corresponding to the forward stagnation point and the magnitude of minimum pressure is acting on the top of the structure a lift force is generated.

Airflow at Mach 2 passes through an oblique shock as shown and deflects 10°. A second oblique shock reflects from the solid wall. What is the pressure ratio (p3/p₁) across the two-shock system? Assume that there is no boundary layer near the wall, so the flow is uniform in each of the regions bounded by the shocks and that y = 1.4. Reflected oblique shock 10° M=2arrow_forward
