Questions below are based on the following information. An engineer is designing a piping system to supply water to a home. Two studies are conducted to determine the effects on volumetric flow rate of the water when the pipe diameter and water velocity are varied. Volumetric flow rate is measured in gallons per minute (GPM), and represents how much water can be supplied to a home in a given amount of time.

Questions below are based on the following information.

An engineer is designing a piping system to supply water to a home. Two studies are conducted to determine the effects on volumetric flow rate of the water when the pipe diameter and water velocity are varied. Volumetric flow rate is measured in gallons per minute (GPM), and represents how much water can be supplied to a home in a given amount of time.

Figure 1 shows a pipe of diameter D with water flowing through it at a velocity V.

 

Study 1
The diameter, D, of the pipe was varied while the velocity of the water, V, was held constant at 5 feet per second (ft/s).

Figure 2 shows how varying the diameter, which was measured in inches, changed the flow rate.

 

Study 2
The velocity, V, of the water flowing in the pipe was varied while the diameter of the pipe, D, was held constant at 1 inch.

Figure 3 shows how varying the velocity changed the flow rate.
