## How do you find the density of a mean?

The mean density is obtained by simply dividing the mass by the volume.

### What is the density of liquids?

Density= Mass/Volume where mass is that for just the liquid (you must subtract out the mass of the graduated cylinder). Now let’s calculate the densities of the two liquids using the following given data.

**What is the highest density liquid?**

Mercury

**Which is more dense milk or water?**

The natural density of milk is 1

## Which is more dense liquid or gas?

Physical Properties of Liquids. Density: The molecules of a liquid are packed relatively close together. Consequently, liquids are much denser than gases. The density of a liquid is typically about the same as the density of the solid state of the substance.

### Is olive oil less dense than water?

Not surprisingly, the olive-oil floats in water, having a less density than it.

**Does pressure depend on mass?**

The pressure exerted by a static fluid depends only upon the depth of the fluid, the density of the fluid, and the acceleration of gravity. The most remarkable thing about this expression is what it does not include. The fluid pressure at a given depth does not depend upon the total mass or total volume of the liquid.

**How do you find density with pressure and height?**

P=hÏg P = h Ï g , where P is the pressure, h is the height of the liquid, Ï is the density of the liquid, and g is the acceleration due to gravity.

## How does density affect flow rate?

The density of a fluid affects its viscosity. Fluids with more mass per unit volume are heavier and require more energy to move them and shear less easily.

### What is mass flow rate equal to?

We can determine the value of the mass flow rate from the flow conditions. A units check gives area x length/time x time = area x length = volume. The mass m contained in this volume is simply density r times the volume. To determine the mass flow rate mdot, we divide the mass by the time.

**How do I find mass flow rate?**

Mass flow rate can be calculated by multiplying the volume flow rate by the mass density of the fluid, Ï. The volume flow rate is calculated by multiplying the flow velocity of the mass elements, v, by the cross-sectional vector area, A.
