if this is weong please tell me
Answer
Given,
Air enter density, ρ₁ = 2.21 kg/m³
speed of entry, v₁ = 40 m/s
Air exit density , ρ₂ = 0.752 kg/m³
speed of exit, v₂ = 180 m/s
Inlet area = 90 cm²
a) mass flow rate through nozzle.
m = 0.796 kg/s
b) exit area
Using continuity equation
Exit area of nozzle is equal to
Yes; form the outermost layer it goes: exosphere, thermosphere, mesosphere, stratosphere, and troposphere(the troposphere is where we live).
