Drag coefficent

Hello
I am calculating the drag coefficient of an array of cylinders (120 cylinders). I am using this expression, sum( -reacf(u)2, x, 1,120)/(spf.rhoU_mean^2*0.01) which says drag force summation from 1 to 120 cylinder having ‘U_mean’ velocity and ‘d’ diameter. However, it does not seem to work. Could you please suggest a correction in this expression?
Thank you
