1. Consider Northrop's T-38 Talon aircraft. It normally flies at a speed of Mach 0.85 at 35,000 feet standard altitude. The air loses velocity as it reaches the inlets or inlets since the motors can only accept a mass flow ð‘šÌ‡ of 44 ð‘˜ð‘” / ð‘ . Air enters the inlets at a temperature of âˆ’38 Â° ð¶.

a. What is the total area of â€‹â€‹the inlets in ð‘š2?
b. At what speed in ð‘˜ð‘š / hð‘Ÿ does this plane fly?
c. At what speed in ð‘˜ð‘š / hð‘Ÿ does the air enter the inlets?
d. The system is in "steady-state" or equilibrium. The flue gases have ð›¾ = 1.29 and ð‘… = 318 ð½, and the output area is 0.4 ð‘š ^ 2. If the pressure and temperature of the gases is ð‘˜ð‘”ð¾ 0.21 ð‘Žð‘¡ð‘š and 600 ð¾, what is the Mach of these?

2. The same airplane uses a Pitot tube to obtain the speed during its takeoff. If the takeoff speed at sea level (standard) is 257 km per hour, which is the measure of total pressure?

3. During a standard day, a truck travels on the express at 120 km per hour. The glass of your cabin has an area of â€‹â€‹2 square meters normal to the direction of movement.

a. What is your best estimate of the force felt by the truck due to this interaction between air and glass?
b. If the driver opens his window, how much suction (ð‘ƒð‘Ž) does he feel?
