//At the given Temperature =T and Pressure P, the required heat Qr to geberate steam from feed water is calculated from the steam table.

//In the calculation part, the book has taken percentage of sulphur dioxide p = 10.6 in the place of p = 10.2, so there exists a deviation in answer
Q_in = ((Pr*pr_rate)/p) * Sp_1 * T1;// Heat content of the inlet gas in J/s

S = Qa/Qr;// in kg/s
printf('The steam production is %.3f kg/s',S)//Deviation in answer is due to some wrong value substition as discussed above
