The lignin contents and higher heating values (HHV) for some of the biomass samples are given in the following Table: With the help of the above data, develop a mathematical model which correlates higher heating values and the lignin contents. After finding the mathematical correlation between HHV and L in question (12), determine the square of correlation coefficient (R2) and also calculate percentage of average error, and what is the root mean square error (RMSE)? Note: The correlation: RMSE =ni=1N1(Observedvalue-Predictedvalue)2 may be used. The proximate and ultimate analyses results of some of the bioresources are given in the Table below: db: Dry basis daf: Dry, ash-free basis, M:Moisture, VM: Volatile Matter, A: Ash, FC:Fixed Carbon Using the correlations: HHV(MJ/kg)=(0.3536FC+0.1559VM0.0078Ash) and HHV(kJ/kg)=(3.55C2232C2230H+51.2CH+131N+20600) based on proximate and ultimate analyses, respectively, predict the lignin contents present in the bioresources by using the correlation developed for the data in question (12)
