Plotting Drag Forces vs (Velocities and Drag Coeff) Over A Moving Body in Python

1) File Parsing Definition: Parse essentially means to ''resolve (a sentence) into its component parts and describe their syntactic roles''. In computing, parsing is 'an act of parsing a string or a text'. [Google Dictionary]File parsing in computer language means to give a meaning to the characters of a text file as per…

1) Integration/Area Under Curve 1.1 PV Diagram  In thermodynamics, a PV diagram is a plot which shows the relationship between the pressure and volume for a particular process.  We know that ` dw = p.dv` is the small work done by the process at a particular instance. Hence, total work done by a process from…

Problem: Minimize: `5-(x-2)^2 -2(y-1)^2`; subject to the following constraint: `x + 4y = 3` 1) Lagrange Multipliers Lagrange multipliers technique is a fundamental technique to solve problems involving constrained problems. This method is utilised to find the local minima and maxima subjected to (at least one) equality…

Curve Fitting Curve fitting is a process of determining a possible curve for a given set of values. This is useful in order to estimate any value that is not in the given range. In other words, it can be used to interpolate or extrapolate data. A good curve fit is one which will be able to predict and explain the trend…

Curve fitting is a process of determining a possible curve for a given set of values. This is useful in order to estimate any value that is not in the given range. In other words, it can be used to interpolate or extrapolate data. Polynomial curve fitting or Polynomial Regression is a process where the given data-set curve…

1. Genetic Algorithm A Genetic Algorithm is an optimisation technique which is used to minimise a certain function. When used in optimisation, generally its purpose is to minimise the error of a function. It is often used in curve fitting. This algorithm is named 'Genetic', because of its structure. It is a '…

Curve fitting is a process of determining a possible curve for a given set of values. This is useful in order to estimate any value that is not in the given range. In other words, it can be used to interpolate or extrapolate data. We can fit a curve either by using the polynomial regression (check out: Polynomial Curve-fitting,…

A code in MatLab to plot the PV Diagram and Thermal Efficiency of an Otto Cycle. Explanations are given in the comments following the code parts. The relationship between the crank-angle and Volume-traced is used in the code to derive the adiabatic curves. Thermal Efficiency has been calculated by the general otto…

Otto Cycle An Otto cycle is an idealized thermodynamic cycle that describes the functioning of a typical petrol or spark-ignition piston engine (Otto engine). The Otto cycle is a description of what happens to a mass of gas as it is subjected to changes in pressure, temperature, volume, addition,…

**This project parses the NASA Polynomials file in an interactive programme where the user can enter the name of a species (which exists in the data file), and the code creates and stores the plots of specific heats, entropies, and enthalpies of the species in particular folders. **   A) File Parsing Meaning:…

2D Animation In Python: A basic robotic arm has two essential parts: the main arm and the manipulator. The main arm is the backbone or the support and can rotate with the base and lean in or out based on the requirements. Thus, the arm defines the reach of the robot. The manipulator or grabber is the end part attached…

This program code in python helps to visualise the effect of the drag forces on a moving body at different speeds and at different drag coefficients.   Drag Force The drag force is a type of fluid friction or resistance which is experienced by a body moving inside a fluid medium. Depending upon the type of the…
