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

Explanation:
From the question we are told that
The mass of the stone is
The height above the top of the water is
The depth of the well is
The gravitational potential of the stone before it was released is
substituting values
The gravitation potential of the stone when it reaches the bottom of the well is
The negative shows that the potential energy of the stone as compared to the earth is reducing
substituting values
The change in the systems gravitational potential is
substituting values
