syms r
expr= 2*pi*rho*(omega- W/2)*W*r^3;
F = int(expr,a,b) ,it computes the definite integral of expr from a to b.

Assuming omega is a numeric vector and that an output is to be created for each:
syms pi rho Omega W r R
expr = 2*pi*rho*(Omega- W/2)*W*r^3;
Tn_inf = int(expr, r, 0, R);
all_Tn_inf = subs(Tn_inf, Omega, omega);
