What else can I help you with?
Would you expect to change a liquid's density?
The temperature of the fluid
Does the size of the column affect the amount of hydrostatic pressure?
Yes, the height and density of the column do affect the amount of hydrostatic pressure. The pressure exerted at the base of a column of fluid is directly proportional to the height of the column of fluid and the density of the fluid. A taller or denser column will result in a greater hydrostatic pressure at the base.
How do you predict if substances will float on another?
Substances will float on another if the density of the object is less than the density of the fluid it is placed in. This is because objects with lower density will displace an amount of fluid equal to their weight, causing them to float. The concept is known as buoyancy.
Must the flow of a compressible fluid be treated as compressible?
No, if the pressure difference results in a density change of less than thirty percent (30%) the fluid may be treated as incompressible by assuming the density of the fluid equals the average density and that the density is constant.

If you had a bathtub full of water would the density of all of the fluid in the tub be the same as only 1 gram of the liquid?
No, the density of a bathtub full of water would not be the same as just 1 gram of water. The density of water is a constant value regardless of the amount of water present. Density is defined as mass per unit volume, so 1 gram of water would have the same density as any volume of water.
What determines the amount of pressure in a fluid?
change in elevation and change in density
What do you do if you poured transmission fluid where the oil goes?
Change the oil
What if you poured a little brake fluid in transfer case?
Change and flush the transfer case fluid immediately.
What should you do if you accidentally poured brake fluid in the oil reservoir?
Change oil and filter
How can you use density to determine whether an object wil float or sink in a fluid?
If the density of an object is less than the density of the fluid, the object will float. If the density of an object is greater than the density of the fluid, the object will sink. This is because objects with lower density than the fluid displace an amount of fluid equal to their own weight, causing them to float. Objects with higher density displace an amount of fluid less than their own weight, causing them to sink.
What would you expect to change a liquid density?
temperature of the fluid.
Does the density of a fluid change when it is compressed?
The density of a fluid will increase according to applied pressure. Even water can be compressed so much that it eventually turns into a metallic substance. Compressed fluids will however not remain in this state when pressure is released.
What happens to the density of a fluid if you change its mass but keep the volume constant?
If you change the mass of a fluid while keeping the volume constant, the density of the fluid will change. Density is calculated as mass divided by volume, so if the mass changes but the volume stays the same, the density will increase if the mass increases and decrease if the mass decreases.
Would you expect to change a liquid's density?
The temperature of the fluid
Does a fluid's density change when it is compressed and attenuated?
Yes it does change because its mass does not change but its volume does. When it is compressed the density will increase because its volume does. When it is attenuated will decrease because the volume does. Density is mass over volume. Remember: it only works because its mass stays the same and the volume changes.
What happens when pressure in a fluid changes?
When pressure in a fluid changes, the volume and density of the fluid may also change. If the pressure increases, the volume decreases and the density increases, leading to compression of the fluid. Conversely, if the pressure decreases, the volume increases and the density decreases, causing expansion of the fluid.
