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.
A material has a coefficient of volume expansion of 60×10^-6/degree celsius. What is its coefficient of expansion?
The coefficient of volume expansion is the triple of the linear expansion coefficient. So with a volume expansion coefficient of 60×10^-6/°C, the linear expansion coefficient would be 20×10^-6/°C.
Why liquids have two coefficient of expansion?
Liquids have two coefficients of expansion because they can expand in both volume (volume coefficient of expansion) and in area (area coefficient of expansion) when heated. The volume coefficient of expansion relates to changes in the volume of the liquid, while the area coefficient of expansion relates to changes in the surface area.
What is the coefficient of the volume of expansion of turpentine?
The coefficient of volume expansion of turpentine is typically around 9 x 10^-4 per degree Celsius. This coefficient indicates how much the volume of turpentine will increase for a one-degree Celsius increase in temperature.
What is the relation between the coefficient of linear and superficial and volume expansion respectively?
The coefficient of linear expansion (α) is one-third of the coefficient of superficial expansion (β), and the coefficient of superficial expansion is one-third of the coefficient of volume expansion (γ). This relationship follows from the dimensional analysis of the expansion coefficients in the respective directions.
Water expands as it freezes can you define a coefficient of volume expansion for the freezing force?
The coefficient of volume expansion for freezing force is a measure of how much a material's volume changes when it freezes. It quantifies the increase in volume as a material transitions from liquid to solid state. For water, this coefficient is positive, indicating that its volume expands when it freezes due to the formation of hexagonal ice crystal structures.
What is the volume coefficient of expansion for ice?
The volume coefficient of expansion for ice is approximately 0.090 × 10^-3 per degree Celsius. This means that for every degree Celsius increase in temperature, ice expands by about 0.090 × 10^-3 of its original volume.
Does mercury have the highest coefficient of volume expansion known?
Yes, mercury has one of the highest coefficients of volume expansion known among common substances. Its coefficient of volume expansion is approximately 181 x 10^-6 per degree Celsius.
What is formula for block coefficient?
The block coefficient (CB) is calculated as the ratio of the underwater volume of a ship's hull to the volume of a rectangular block that has the same overall length, breadth, and draft as the ship. The formula for block coefficient is: [ CB = \frac{V_{ship}}{L \times B \times T} ] Where: CB = Block coefficient Vship = Underwater volume of the ship's hull L = Length of the ship B = Breadth of the ship T = Draft of the ship
Why the coefficient of volume expansion of the water different with coefficient of volume expansion of the ethanol?
The coefficient of volume expansion for a substance is determined by its molecular structure and interactions between its molecules. Water and ethanol have different molecular structures and intermolecular forces, which result in different coefficients of volume expansion. Water has a higher coefficient of volume expansion than ethanol because of its hydrogen bonding and unique properties.
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).
What are the Units of Einstein coefficient?
The units of Einstein coefficient are m^3/s. This unit represents the volume per unit time over which a transition occurs in a material.
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.)
