**Question:**

Which fluid requires a larger pump to deliver the same fluid velocity through the same piping system at room temperature: water or engine oil? Explain.

**Explanation:**

When determining the size of the pump required to deliver the same fluid velocity in water and engine oil through a piping system at room temperature, consideration of the fluids' viscosities is essential. Engine oil is more viscous than water, which means it has a greater resistance to flow. This higher viscosity results in increased friction losses within the piping system. Consequently, a larger pump is required to overcome these friction losses and achieve the same fluid velocity as water, which flows more easily due to its lower viscosity.

In summary, engine oil requires a larger pump compared to water to maintain the same flow velocity in identical conditions.
