What is the power law formula?

A power law distribution has the form Y = k Xα, where: X and Y are variables of interest, α is the law’s exponent, k is a constant.

What is Powerlaw relationship?

A power law is a relationship in which a relative change in one quantity gives rise to a proportional relative change in the other quantity, independent of the initial size of those quantities.

What is power and SI unit?

We can define power as the rate of doing work, it is the work done in unit time. The SI unit of power is Watt (W) which is joules per second (J/s). Sometimes the power of motor vehicles and other machines is given in terms of Horsepower (hp), which is approximately equal to 745.7 watts.

What is the power law coefficient?

Polymers can be described by the power-law coefficient, which is a simple relationship derived from the shear-rate/viscosity curves at different temperatures. It describes the viscosity in most of the processing range of the extruder.

What are the 3 laws of exponents?

Rule 1: To multiply identical bases, add the exponents. Rule 2: To divide identical bases, subtract the exponents. Rule 3: When there are two or more exponents and only one base, multiply the exponents.

What is a scaling exponent?

The scaling exponent reflects the presence of correlations and in the presence of nonstationarity and periodicity, such as intermittency exhibited by many systems, detrending of the data is widely used in the computation of the scaling exponents from time series data.

What is watt Class 9?

Watt, denoted by W, is a unit of power. In the International System of Units (SI) it is defined as an amount of 1 Joule energy used per sec, and is used to quantify the rate of energy transfer with respect to time. In SI base units, the watt is described as kg m2 s-3.

What is the SI unit of water?

S.I units of water is measured in terms of liters .

How do you calculate the power dissipated in a resistor?

Divide the voltage by the total resistance to get the total current in a series circuit. In a series circuit, the same current flows through each resistor. Multiply the square of the current with the individual resistances to get the power dissipated by each resistor.

How do you find the power law constant?

n and K can be calculated from any two value of shear rate and shear stress. The method of reading shear rate on the rig comes from a V-G meter. Typically, 600 rpm, 300 rpm and 3 rpm are obtained from every mud test and we can use those reading to determine n and K.
