The pressure needed at point (1) to produce the flow where water "bubbles up above the exit of the vertical pipe attached to three horizontal pipe segments is 0.750 psi.
<h3>What is Bernoulli's equation?</h3>The Bernoulli's equation for incompressible fluid can be given as,
Here, ρ is density of fluid, g is acceleration due to gravity, (P) is the pressure v is velocity, h is height of elevation and subscript (1 and 2) is used for point 1 and 2.
Water "bubbles up" h2 = 9 in. Above the exit of the vertical pipe attached to three horizontal pipe segments.
The total length of the 1.75-in.- diameter galvanized iron pipe between point (1) and the exit is 21 inches. h3 = 18 in.
Reynolds number is,
The formula for the ratio of pressure to radius, when pressure and velocity at point 2 is zero can be given as,
Here, f=0.039 and ∑K(L)=4.5. Put the values,
Put the value of r we get,
The pressure needed at point (1) to produce the flow where water "bubbles up above the exit of the vertical pipe attached to three horizontal pipe segments is 0.750 psi.
