# Differential equations

d(y) / d(W) = -alpha/(2*y) * (1+eps*X) 
y(0) = 1.0
d(X) / d(W) = -rAdash / FA0 
X(0) = 0


# Constants
FA0   = 0.1362  # [mol/s]
kdash = 0.0074  # [mol/(kg catalyst . s)]
alpha = 0.0367  # [1/kg]
eps   = -0.15   # [-]

# Algebraic equations
rAdash = -kdash * (1-X)/(1+eps*X) * y
flow_ratio = (1 + eps*X)/y

# Initial and final values for independent variable:
W(0) = 0
W(f) = 20
