How does fluid density affect fluid speed? Basically I am trying to figure out if, with all other quantities remaining constant, would an increase in fluid density cause the fluid speed to increase/decrease? For example, would water and honey have different fluid speeds in a pipe, because their densities are very different? I know that:
$$Av = Av$$
$$P + ρgh + (1⁄2) ρv^2$$
But does an increase in density lead to an increase/decrease in fluid speed? How so?
