Answer to Question #250187 in Electrical Engineering for Mangi

Question

Derive discharge coefficient

Answer 1

Function 'calFlowRate' :-

function [Q] = calFlowRate(Cd, theta, h)

%Converting angles into radians

theta = theta.*(pi()/180);

  

g = 9.81;

%l_Cd is the length of the vector Cd

l_Cd= length(Cd);

  

%Initializing the discharge matrix which size is same as size of Cd

Q = zeros(l_Cd,1);  

%Using for loop to calculate discharge for corresponding Cd,theta and h

  

for i = 1:l_Cd

%Computing discharge by formula of V notch

Q(i,1) = (8/15)*Cd(i)*((h(i))^2.5)*sqrt(2*g)*tan(theta(i)/2);

  

end

  

end

Script 'LastnameLabProb1' :-

%defining our Cd, theta and h matrices

Cd = [0.52, 0.82];

theta = [60, 45];

h = [1.7, 3.4];

%Calling the function calFlowRate to calculate the discharge

Q = calFlowRate(Cd,theta,h);

%Displaying the discharge matrix

disp('Discharge matrix = ');

disp(Q);

First, copy the code of function in MATLAB editor and save it.

Then copy the code of script in another window of the editor and save the run it.

The output of the given problem is

Discharge matrix =

2.6725
