Question

if you see three pipes at a jet pump in the basement it means that the pump is feeding two separate pressure tanks the well must be deeper than 50 feet the suction line has been replaced because of obstruction the venturi is in the well or lake or river the system is capable of developing pressures in excess of 50 psi question 24 1 pts how much water flows through a ¾ -inch -diameter pipe relative to a ½ -inch -diameter pipe with the same pressure loss? 150 percent 200 percent 225 percent 250 percent 270 percent

Explanation:

Question 1

Three - pipe jet pump setups often indicate feeding two separate pressure tanks. Other options like well depth, suction - line replacement, venturi location, or pressure development are not directly related to the presence of three pipes.

Step1: Recall flow - rate formula

The flow rate $Q$ is related to the cross - sectional area $A$ of the pipe and the velocity of the fluid. For laminar flow, $Q = vA$. The cross - sectional area of a pipe $A=\pi(\frac{d}{2})^2$.

Step2: Calculate areas for both pipes

Let $d_1=\frac{3}{4}$ inch and $d_2 = \frac{1}{2}$ inch. $A_1=\pi(\frac{d_1}{2})^2=\pi(\frac{3/4}{2})^2=\frac{9\pi}{64}$ and $A_2=\pi(\frac{d_2}{2})^2=\pi(\frac{1/2}{2})^2=\frac{\pi}{16}=\frac{4\pi}{64}$.

Step3: Find the ratio of flow rates

Since for the same pressure loss, the velocity is the same in both pipes (under certain assumptions), the ratio of flow rates $\frac{Q_1}{Q_2}=\frac{A_1}{A_2}=\frac{9\pi/64}{4\pi/64}=\frac{9}{4} = 225\%$.

Answer:

the pump is feeding two separate pressure tanks
