CURVE FITTING USING MATLAB

(a) x is given below. Write an if statement that will print whether x is positive, negative, or zero. x=-10 x = -10 if x == 0: print("x is positive") elif x > 0: print("x is positive") else: print("x is negative") (b) x and y are given below. Write an if statement that will print whether x and y are both positive, or…

Aim: To Run a pipe flow simulation with an inlet Reynolds number of 100,1000 and 10,000.And for each of these cases to do the following 1. Place line probes at 95%, 90% and 85% of the pipe length. 2. Compare the normalized velocity profile at each of these locations. 3. Normalize the velocity profile by the inlet…

> Curve fit are helpful as they describe  hoe your data changes mathematically. > Below is the programs for curve fitting using MATLAB. > In these programs our main motive is to predict the values of specific heat with respect to        temperature to get a better fit. >As we can analyse…

AIM :- To write codes on Matlab for simulation of the simple pendulum. We are going to use second oder differential equation to solve the simple pendulum simulation problem `(d^2theta)/(dt^2)+b/m(d theta)/(dt) + g/l sin(theta) = 0`. form above equation we will create two ODE ie `(d theta1)/dt = theta2`, and `(d theta2)/dt…

Air Standard Otto Cycle -:     Otto cycle is also called the constant volume cycle as the heat addition and heat rejection is done at a constant volume. Otto cycle is used in petrol and many other gas engines. It consists of two reversible constant volume processes and two adiabatic processes. Efficiency…

PART-1:- Drag force Vs Velocity When a cyclist ride a bicycle he is introduced to some resisting force developed by the air and this force is known as drag force . As the speed increases drag forces also increases keeping this concept in mind we have to write a programme in python to calculate the drag force. As we Know…

For optimization we need to install a package GEKKO using PIP.  Consider the design of a simple tubular symmetric truss shown in Fig. 1.1 below. A design of the truss is specified by a unique set ofvalues for the analysis variables: height (H), diameter, (d), thickness (t), separation distance (B), modulus of elasticity…

1. a) Popt: Its a kind of array which gives the Optimal values for the parameters so that the sum of the squared residuals of f(xdata, *popt) - ydata is minimized. In simple language popt represents the coefficients defined in the function Ex. def func ( a,b,c) here a,b,c are the coefficients…

To Minimize the fuction 5 - (x-2)² - 2 (y-1)² subjected to constraint x+4y = 3 using Lagrange multiplier method.   Solution:  To solve this problem we will use Lagrange method for constrained minimization According to Lagrange, L =  f - λg Where, f = 5 - (x-2)² - 2 (y-1)²…

Before Writing the codes We should have a basic knowledge about the Robotic field. Robotics is an emerging field nowadays. It is a multidisciplinary science, encompasssing a number of fields like Computer technology, Mechanical design, control engineering, Sensing, Kinematics and dynamics of machinery and manufacturing…

1) For calculating the Air flow rate for a Brayton cycle the we'll use the formula W = Cp[(t3-t4)-(t2-t1)]. 2) Brayton cycle consist of two Reversible constant pressure and two reversible adiabatic Process. 3) Heat addtion and rejection happens in constant pressure processes. 4) The efficiency of the Brayton cycle is given…
