Derivation of gibbs-duhem-margules equation using gibbs-duhem equation?
Gibbs-duhem-margules equation and its derivation
How do you find the equation of a tangent line?
In order to find the equation of a tangent line you must take the derivative of the original equation and then find the points that it passes through.
A value for a variable that makes the equation true?
That's the "solution" to the equation described by the sentence.
How do you solve the equation -4.8 6.4-8.48?
To solve the equation -4.8 + 6.4 - 8.48, you first add the -4.8 and 6.4 together to get 1.6. Then, you subtract 8.48 from 1.6 to get -6.88. Therefore, the solution to the equation is -6.88.
What is a polynomial equation of degree two called?
quadratic
Who invented saybolt viscometer?
The Saybolt viscometer was invented by J. W. Saybolt in the early 20th century as a method to measure the viscosity of petroleum-based fluids like oils. It is commonly used in the petroleum industry to determine the flow properties of various fluids.
What is the basis for classification of redwood viscometer?
REDWOOD'S Viscometer is used to find out the viscosity of an standard rape oil and any of the fluids . The viscometers are classified into 4 types they are 1. Saybolt Viscometer 2. Engler Viscometr 3. Barbey Viscometer & 4. Redwoods Viscometer
What number is the saybolt color water white?
30
Why is capillary tube fixed in Ostwalds viscometer?
The capillary tube is fixed in the Ostwalds viscometer is for passing the liquid.
How is viscosity measured?
viscometer
What is the saybolt color test?
The Saybolt color test is a method used to determine the color of refined petroleum products like diesel, gasoline, and jet fuel. It involves comparing the color of the sample to standard color solutions and assigning a Saybolt color number to represent its hue and purity. Lower Saybolt color numbers indicate darker or more impure products, while higher numbers indicate lighter or purer products.
Construction and working of capillary flow viscometer?
A capillary flow viscometer, or Ostwald viscometer, consists of a U-shaped glass tube held vertically in a controlled temperature bath. It was named after its inventor, Wilhelm Ostwald.
Why viscometer is used?
A viscometer is used to measure the viscosity of a fluid, which is its resistance to flow. This measurement is important in various industries such as food processing, pharmaceuticals, and manufacturing, where the viscosity of a fluid can affect product quality and performance. By using a viscometer, manufacturers can ensure consistency in their products and adjust formulations as needed.
Is Ostwalds viscometer used to measure viscosity of more viscous oil?
Yes, the Ostwalds viscometer can be used to measure the viscosity of more viscous oil.
What is A and B in redwood viscometer?
In a redwood viscometer, A and B are constants used in the formula to calculate the viscosity of the fluid being tested. The formula is viscosity = A + B * time in seconds. The values of A and B are specific to the design of the redwood viscometer and are typically provided by the manufacturer.
What is the essential difference between Ostwald and Ubbelohde viscometer?
The essential difference between Ostwald and Ubbelohde viscometers is the method of measuring viscosity. Ostwald viscometer measures the flow time of a fixed volume of liquid through a capillary, while the Ubbelohde viscometer measures the flow time of a fixed volume of liquid out of a calibrated capillary. Additionally, the Ubbelohde viscometer is more accurate and suitable for measuring the viscosity of transparent liquids.
Why the Ostwald's viscometer is kept vertically during experiment?
if we put viscometer horizontally, movement of liquid in the tube is not properly and time required by liquid which helps in calculation of viscosity of fluid
