'Dielectric constant' is an archaic term for relative permittivity. They are one and the same.

What are the types of humidity transducers?
three types relative humidity, absolute humidity, specific humidity. The detecor transducers generally consist of two capacitor plates enrgised by an alternating signal. The water vapour in the air changes the dielectric between the plates and alters the frequency of the capacitor network. Thus humidiy is changed to a varying frequency which can be counted and displayed digially.
Is there a pumping system which variable speed drive is not recommended?
Most centrifugal chillers require a constant water flow, therefore a VFD would not be of any use.
What are the future advantages of water level controller?
This product is designed to automatic control of motor, which ensures constant reserve of water in storage tanks. Automatic water level controller is used to automatically fill the over head tank as and when it gets empty and monitor the water level in it. Automatic water level controller switches ON the motor when the water level in the overhead tank drops below pre fixed low level(on point) and puts off the motor when water level rises up to pre fixed high level (off point) motor also switches off when the sump water is exhausted before filling overhead tank, pump running dry, Mains voltage fluctuations.
What is the impedance of water?
Impedance of water is the density of water times the sound velocity in water ANSWER: Pure water has a high resistivity. An ohmmeter i a good way to check for quality of water. If resistance is low it means that it is has other material floating in there.
The presence of these in water causes water to conduct electicity?
Pure water, by itself, is not capable of conducting electricity. However, when other substances are added and ions make their way into water, those free ions can cause water to conduct electricity.
What is magnetic permeability of materials?
Relative permittivity or dielectric constant of a medium is defined as the ratio of force between two charges separated by a certain distance in air or vacuum to the force between the same charges separated by the same distance in the medium.According to American Heritage Dictionary:permittivitySYLLABICATION: per·mit·tiv·i·tyPRONUNCIATION: PERM eh TIV eh TEENOUN: Inflected forms: pl. per·mit·tiv·i·tiesA measure of the ability of a material to resist the formation of an electric field within it. Also called dielectric constant, relative permittivity.
What is dielectric constant?
A dielectric is an insulating material that does not conduct electricity and is transparent to an electromagnetic field. Dielectric materials are used to separate conducting surfaces such as the plates inside a capacitor, wires inside transformers, electric cable conductors, and elsewhere in the electric industry where electrical separation of charged elements is necessary. The dielectric constant is a ratio of the capacitance of a capacitor in which a particular insulating material is the dielectric, to the capacitance of the capacitor in which a vacuum is the dielectric.
What is the effect of dielectric constant of water on the solubility of the ionic salt?
Water has a very high dielectric constant so when an ionic salt is placed in water it ionizes and water molecules react with ions of solute and make a solution
Can the dielectric constant of carbon in water be measured?
dielectric constant is a property of a material, this question is asking the property of a two mixed together, in an undeclared ratio. But yes dielectric constants can be measured. The problem you will have is keeping a uniform mix.
What are some examples of a chemical property for water?
It has a very high dielectric constant
How water is dielectric constant?
The dielectric constant of water varies with temperature and is approximated by this polynomial equation: E = 87.740 - 0.40008*t + 9.398*(10^-4)*t^2 - 1.410*(10^-6)*t^3
Why do polar substance have a high dielectric constant?
Water, due to its polar nature, has a large dielectric constant. Therefore, water molecule has a very large electric dipole moment and is forced to rotate to respond to an alternate external electric field. Hence water as a liquid has a very large dielectric constant i.e. 80. Mica on the other hand is less polar as water and hence has low dielectric constant.
Which dielectric in this world has highest dielectric constant?
Strontium Titanate has a dielectric constant of 233. TDK in Japan makes Ultra-high Voltage Ceramic Capacitors using this as the dielectric material. Compared to distilled water at 76.7 - 78.2 (lowers as temperature rises). Types of glass can vary between 4 and 10.
What is the much more polar solvent?
Formamide is the most polar solvent. It has a dipole moment of 3.73 and a dielectric constant of 109. As a comparison, water has a dipole moment of 1.85 and a dielectric constant of 80. The higher the dipole moment value and the dielectric constant, the more polar the solvent. At the opposite, the less polar solvents are hexane, benzene and carbontetrachloride.
Why does water dissolve things well?
this is because water has a high dielectric constant of about 81.thus it can break the forces of attraction in most substances.
What is a dielectric?
In physics, a dielectric is an insulating (or very poorly conducting) material. The material can be solid, liquid or gaseous. When a voltage difference is applied to top and bottom of a cylinder filled with a dielectric, no current will flow inside the cylinder because, unlike metals, a dielectric has no free-or loosely bound-electrons that can drift through the material. Instead, electric polarization occurs. The positive charges within the dielectric are displaced minutely in the direction of lower voltage, and the negative charges are displaced minutely in the opposite direction. When the molecules constituting the dielectric are polar (like water molecules), the molecules will align in the field, thus contributing to the electric polarization. Inside the cylinder no net charge density will arise because the charges in adjacent volume elements cancel. However, at the top and bottom of the cylinder an uncanceled surface charge will appear, and this surface charge (positive at the low voltage side and negative at the high voltage side) will oppose the electric field associated with the voltage difference. Thus, the polarization of the dielectric reduces the electric field inside the dielectric. Dielectric material is characterized by an intrinsic property called relative permittivity, usually denoted by εr (formerly this was known as the dielectric constant). The relative permittivity describes the ease of the polarization of the material and determines the size of the surface charge densities at the top and bottom of the cylinder. The Coulomb force between two permanent electric point charges placed inside a dielectric medium is 1/εr smaller than it would be in a vacuum due to the polarization of the dielectric medium by the point charges. The quantity of electric energy stored per unit volume of a dielectric medium is proportional to εr. The capacitance of a capacitor filled with a dielectric is a factor εr greater than it would be in vacuum.

Why do sodium ions and chloride ions remain dissociated in the blood?
Blood has a sufficiently high proportion of water to have a large enough dielectric constant to promote the dissociation of the ions.
