Establishment of task:
The process of granulation of carbamide was carved at the granulation tower. To obtain the mathematical dependency of the output parameter (u) from factors (Xi) realizations complete factor experiment 23.
X1 - density blue, g/m3,
H2 - weekend temperature, C,
H3 - time of stay at the tower, hv.
The size of the granul, mm.
Plan of the experiment of representations in Table 1, and the results of parallel observations in Table 2.
Examine the calculations of the coefficients at the equation of regression, verify their significance, assess the adequacy of the mathematical model.
