Flow over bicycle

%flow over bicycle
%calculating the drag force
%Inputs
%Density kg/m^3
rho = 1.225;
%Frontal Area m^2
A = 1;
%Drag Coefficient
Cd=[0.45;0.7;1.14;1.28;2.95];
% Velocity m/s
v = (1:10);
% Drag Force
Fd = 0.5.*Cd*v.^2*A*rho;
plot(Cd,Fd)
grid on
xlabel(\'velocity\');
ylabel(\'Drag Force\');

Results:-

Drag coefficient vs Drag force

shape of the object plays a major role in the amount of drag force generated by it,as shape changes drag coefficeint changes so does the drag force

in the graph we can see with increase in drag coefficient drag force is increasing
