If a stick travels 60 ft in 40 seconds, what is the flow velocity in the sewer?

If a stick travels 60 ft in 40 seconds, what is the flow velocity in the sewer?

• A. 0.5 ft/sec
• B. 0.67 ft/sec
• C. 1.0 ft/sec
• D. 1.5 ft/sec

Answer: (D)

To determine the flow velocity of the stick in the sewer, you need to use the formula for velocity, which is defined as the distance traveled divided by the time taken. In this scenario, the stick travels a distance of 60 feet in a time period of 40 seconds. To calculate the flow velocity, you would perform the following steps: 1. **Distance traveled:** 60 feet 2. **Time taken:** 40 seconds The formula for calculating velocity is: \[ \text{Velocity} = \frac{\text{Distance}}{\text{Time}} \] By substituting the values into the formula: \[ \text{Velocity} = \frac{60 \text{ ft}}{40 \text{ sec}} \] When you calculate this, you find: \[ \text{Velocity} = 1.5 \text{ ft/sec} \] This value indicates that the flow velocity of the sewer is 1.5 feet per second, which is why this option is the correct answer. It accurately reflects the rate at which the stick moved through the sewer system over the given time period. Understanding this concept of velocity is essential in wastewater management, as it can influence the design

To determine the flow velocity of the stick in the sewer, you need to use the formula for velocity, which is defined as the distance traveled divided by the time taken. In this scenario, the stick travels a distance of 60 feet in a time period of 40 seconds.

To calculate the flow velocity, you would perform the following steps:

1. Distance traveled: 60 feet

2. Time taken: 40 seconds

The formula for calculating velocity is:

[

\text{Velocity} = \frac{\text{Distance}}{\text{Time}}

]

By substituting the values into the formula:

[

\text{Velocity} = \frac{60 \text{ ft}}{40 \text{ sec}}

]

When you calculate this, you find:

[

\text{Velocity} = 1.5 \text{ ft/sec}

]

This value indicates that the flow velocity of the sewer is 1.5 feet per second, which is why this option is the correct answer. It accurately reflects the rate at which the stick moved through the sewer system over the given time period.
