The values of the variables are in Matlab code.

g = 32.17; % gravitational constant
V2 = sqrt(2*g*h*778) % adiabatic velocity
U_Vo = 0.41; % velocity ratio
U = U_Vo * V2; % velocity of the blade
N = 3600; % shaft rotation
rm = (U*60)/(2*pi*N) % midline radius
alpha_2 = [8,9,10,11,12]; % angle made by absolute velocity of steam with tangential direction
alpha2 = alpha_2.*(pi/180)
W2 = sqrt(V2.^2 + U.^2 - 2.*V2.*U.*cos(alpha2)); % relative velocity

B3 = beta2;
B_3 = B2;
V3 = sqrt(W3.^2 + U.^2 - 2.*W3.*U.*cos(B3)) % velocity of steam at rotor exit
alpha3 = asin((sin(B3).*U)./V3) + B3;
