According to Bernoulli's principle, is the fertilizer solution in Figure 13-2 pulled or pushed up
the tube (B)?

Respuesta :

Answer:

It is pushed up the tube.

Explanation:

Answer:

The solution is pulled up the tube

Explanation:

In the figure attached, the Figure 13-2 is shown.

Let's call '1' the beginning of the tube B and '2' the end.

Bernoulli's principle:

[tex] P_1 + \frac{1}{2} \rho v_1^2 + \rho g h_1 = P_2 + \frac{1}{2} \rho v_2^2 + \rho g h_2 [/tex]

where P is pressure, ρ is density, v is velocity, h is height and g is the acceleration of gravity

Given that:

  • In the spray bottle the pressure at 2 is lower than at 1.
  • The velocity is constant through the tube

Then h2 must be greater than h1, so the solution is pulled up the tube
