Coefficient of Volume (Cv) is a factor used in describing the amount of water that will pass through a fully open valve. It describes the flow in gallons per minute (GPM), with a specific gravity of 1, at a temperature of 60 deg F, and a pressure drop of 1 psi. For example, a Cv of 6.0 indicates a flow capability of 6.0 GPM at the above mentioned conditions. For a pressure drop of other than 1 PSI, GPM = Cv*Sqrt(delta P / Specific Gravity), where delta P is in unit of PSI.

Differentiate numeral coefficient from literal coefficient?
numeral coefficient or numerical coefficient is a number used in an algebraic term, while literal coefficient is the letter used to represent a number.
Relationship between coefficient lift and coefficient drag?
For cylinders coefficient of lift is approximately half of coefficient of drag while they are equal for Aerofoils.
What is the coefficient in algebra?
The coefficient in algebra is the number before a letter with an exponent on it. The 3 is the coefficient in this example: 3x7
What is the coefficient of 8x?
The coefficient is the numerical value attached to an unknown or a variable. Thus, the coefficient of 8x is 8.
What is the coefficient of 6N?
If 'N' is the variable, then 6 is the coefficient.
Water expands as it freezes can you define a coefficient of volume expansion for the freezing force?
The coefficient of the thermal expansion of water is equal to .00021. Water expands by 9% of its volume when it freezes.
A material has a coefficient of volume expansion of 60×10^-6/degree celsius. What is its coefficient of expansion?
120×10^-6
What is the formula for calculating volume change due to heat?
That depends on the exact details. For a gas, the ideal gas law is usually a good approximation: other things being equal, the volume is directly proportional to the absolute temperature (that is, the temperature expressed in kelvin). For a liquid or gas, the expansion is much less than in a gas. You can look up the coefficient of expansion for a specific substance, and then use the definition of the coefficient; that is, the volume change is equal to (volume) times (temperature difference) x (coefficient of volume expansion).
An ordinary glass is filled to the brim with 350 mL of water at 100 C If the temperature decreased to 20C how much water could be added to the glass?
Difference in volume = (initial volume) (coefficient of volume expansion of water) (difference in temperature) coefficient of volume expansion of water=0.0002ml/degree celsius (not sure about the value. Better get help from a teacher.)
The volume of this rectangular prism is 5x3. What does the coefficient 5 mean in terms of the problem?
I hope this helps
When can all the coefficient in a balanced equation represent volume ratios?
When reactants and products are gases at STP
Formula for calculating distribution coefficient kd in size exclusion chromatography?
Kd = (Ve - Vo)/(Vt - Vo) Ve = elution volume Vo = void volume Vt = volume total
Explain formula volume expansion coefficient subject expansion of solid?
Formula for the volume Expansion for a solid is αV=1VdVdT and Isotropic materials is αV=3αL.
Why the coefficient of volume expansion of the water different with coefficient of volume expansion of the ethanol?
Since there is extensive hydrogen bonding in case of water (two -OH per molecule) unlike ethanol (which has one -OH per molecule) so the intermolecular force difference is there between water and ethanol. Thus the coefficient of volumetric expansion will also be different, 'coz intermolecular force is a direct variable effecting this coefficient......
Do all solids expand on heating?
Yes, they do. The phenomenon is called thermal expansion. Every substance has a "coefficient of expansion" figured out via experiment. The coefficient is used in the following way. change in length = original length * change in Temperature (K) * coefficient of linear expansion change in volume = original volume * change in Temperature (K) * coefficient of volume expansion The coefficient of volume expansion is three times the coefficient of linear expansion. The unit for the coefficient is "per degree" (this makes more sense when you use it in an equation)
What is the block coefficient of a boat?
It is a ratio obtained by dividing the volume of the hull of the vessel by the volume of a block having the same length, width and height as the vessel's length, beam and depth. It is used to infer how "streamlined" a vessel is. An oil tanker would normally have a larger block coefficient than a container ship.
How do you calculate the weight of a solid object?
Find the volume of the sample (Length times width times height) and multipy by the density coefficient.
