Consider a venturi with a small hole drilled in the side of the throat. This hole is connected via a tube to a closed reservoir. The purpose of the venturi is to create a vacuum in the reservoir when the venturi is placed in an airstream. (The vacuum is defined as the pressure difference below the outside ambient pressure.) The venturi has a throat-to-inlet area ratio of 0.85. Calculate the maximum vacuum obtainable in the reservoir when the venturi is...

B. Consider the flow of air through a convergent-divergent duct, with inlet, throat and exit areas are 6, 4 and 5 m2, respectively. The inlet and exit pressure are 1.01X105 N/m2 and 1X105 N/m2, respectively. Calculate the flow velocity at the inlet, throat and exit. (assume incompressible flow with standard sea-level density).

1. [20 pts] An indraft wind tunnel pulls air into an inlet, through a contraction, the test section, and the diffuser, as shown below. The test section has a circular cross section and it has a diameter of 0.5 m. Assume the wind tunnel is at sea level and the temperature and pressure of the atmosphere are given by standard atmospheric conditions. (a) If the test section is designed to have a velocity of 200 m/s, determine the Mach number,...

Q7. Consider the twin-jet airplane described as follow: wing area = 47 m2, aspect ratio = 6.5, Oswald efficiency factor = 0.87, weight = 103,047N, and zero-lift drag coefficient = 0.032. The airplane is equipped with two jet engines with 40,298 N of static thrust each at sea level. The thrust-specific fuel consumption is 1.0 N of fuel per newton of thrust per hour, the fuel capacity is 1900 gal, and the maximum gross weight is 136,960 N. Calculate the...

W2 U = 150 m/s W1 C1 Z Ol1 2. (40 pts) A very light business jet is in flight at Mach 0.85 at a cruise altitude of 13.5 km (static temperature 216.7 K and static pressure 15.26 kPa). It is powered by two turbofans, each with two independent spools and a thrust rating of 1800 lbf. The low-pressure spool consists of a single-stage fan and a two-stage axial compressor, all powered by a two-stage axial turbine. The high-pressure spool...
