Question

As a fuel saving measure, commercial jets cruise at an altitude of about 10 km. While cruising at an altitude of 10 km, a small leak occurs in one of the window seals in the passenger compartment of a Learjet. Within the passenger compartment, the pressure and temperature are, respectively, 1.03 atm and 20°C and the pressure outside the craft is 0.274 atm. Model the air as an ideal fluid to find the speed (in m/s) of the stream of air flowing through the leak. (Assume the density of air to be 1.20 kg/m³.)
