# An ideal fluid flows through a horizontal tube of varying cross-section. According to Bernoulli’s equation, what is the relationship between the fluid’s speed and pressure?

An ideal fluid flows through a horizontal tube of varying cross-section. According to Bernoulli’s equation, what is the relationship between the fluid’s speed and pressure?

- **A.** The relationship depends on the fluid’s viscosity.
- **B.** Regions of higher speed will have lower pressure.
- **C.** The pressure is independent of the fluid’s speed.
- **D.** Regions of higher speed will have higher pressure.
