Answer: Skinner box
Explanation: Skinner box is referred as the environment to conduct an experiment to observe the natural behavior of the element in a chamber. The Skinner box is also known as operant conditioning chamber. It is most commonly used for the experiments to be conducted with the animals in the operant conditioning chamber for the research purpose.
It is also soundproof tool and also refereed as the lever box as it contains lever .Thus the answer is Skinner box.

<h3>How is boundary layer thickness calculated?</h3>
- Where x is a position parallel to the wall, y is a coordinate normal to the wall, v is a (small) viscosity, u = (u, v) is the velocity, is the vorticity, and so on. The boundary conditions are as follows: u(x,y = +,t) = U, and u(x,y = 0,t) = 0.
- To gauge the overall pressure, a vertically sliding Pitot tube is employed. So that the growth of the boundary layer in the flow direction can be seen, the total pressures can be recorded at various distances from the plate surface. Static pressure is gauged at a different measurement location.
