Plotting Length vs Height

Hello!

I am currently trying to create a GUI that plots length vs height, I'm currently working on the loop to do the length at different values. Whenever I do the loop below, it outputs one value on the graph, how might I do this?

lp = [0:200];

for i=1:length(lp)

SVP = exp(20.386-(5132/(T+273))); % to solve for vapor pressure

constants = (((101*10^3)/(1000*9.81))+3)-(((SVP*10^3)/(1000*9.81))+7); % answer is l/s

constants2 = (D+(f*lp))/(D*2*g);

V3 = (constants/constants2)^(1/3); % in m/s

hp = ((f*(lp/D)*((V3^2)/(2*g)))-2.6681); % important equation here

plot(lp, hp);

end

I am sorry to say but the question is unclear and please provide other constant values which are not defined here.

Also, try:

plot(lp,hp,'*')

What does it show?
