What is mechanistic and empirical models are?
Both of the flow models are used to predict the flow pattern of the complex fluid behavior.Empirical approach use experimental data to make flow models and the correlated parameters are dimensionless. For instance, Moody diagram, where friction factors are the function of Reynolds number. Empirical flow models are hard to improve and usually have errors in the range of 20%.Mechanistic flow models comparing to empirical one, talks about the complex flow occurrences in pipes. "The use of mechanistic models is expected to improve both its accuracy and extrapolation capability to any operation conditions" (Answers.com). The mechanistic model approaches include all important variables - laboratory and field data, which helps to predict methods.

What are the methods in estimation?
There are a few methods in estimation. Like framework, unknown parameters, empirical dist and substitution principle most of these methods can be used using substitution principles.

What are the characteristics of positivist models?
Positivist models are based on the idea that knowledge is derived from observable facts and empirical data. They emphasize objectivity, empirical evidence, and the use of scientific methods to study and understand phenomena. Positivist models seek to establish causal relationships and predict outcomes through systematic observation and experimentation.
