Hi, I am having some trouble with a plot. I am trying to plot pressure vs. time using an equation for pressure with respect to time. Whenever I plot this I get a blank graph, so i’m not sure what the problem is. I appreciate any help!
Po = 400000;
Patm = 101325;
rhowater = 1000;
Vo = .00133333;
Anoz = pi*(.010668)^2;
syms P t
P = Po + (((-1.4*P*((P/Po)^(5/7)))/Vo)*(Anoz*sqrt((P-Patm)/rhowater)))*t;
Eqn = solve(P,t);
Peq = Eqn;
fplot(Peq,[0 1])
ylim ([0 450000])
xlabel(‘time (s) ‘)
ylabel(‘Pressure (Pa) ‘)Po = 400000;
Patm = 101325;
rhowater = 1000;
Vo = .00133333;
Anoz = pi*(.010668)^2;
syms P t
P = Po + (((-1.4*P*((P/Po)^(5/7)))/Vo)*(Anoz*sqrt((P-Patm)/rhowater)))*t;
Eqn = solve(P,t);
