Understand the Problem
The question in the image appears to involve mathematical equations and relationships related to heat transfer or fluid dynamics, likely examining specific parameters and their contributions. The overall goal seems to analyze or derive certain equations based on these parameters.
Answer
The expression for $Q_2$ is $Q_2 = Ns  R  pp  G_0  W$.
Answer for screen readers
The final solution is contingent upon substituting the specific values for the parameters involved. Therefore, without numeric values, the expression for $Q_2$ would remain:
$$ Q_2 = Ns  R  pp  G_0  W $$
Steps to Solve

Identify the parameters in the equations Recognize the variables involved. The equations seem to include $R$, $G$, $W$, $Q_1$, and $Q_2$. Understand what each variable represents in the context of heat transfer or fluid dynamics.

Analyze the first equation The equation given is: $$ Ns = R + pp + G_0 + W + \alpha_2 Q_2 $$ Here $Ns$ appears to represent a total or specific parameter. Rewrite this to isolate $Q_2$ if necessary.

Substitute values if available If specific numerical values for $R$, $pp$, $G_0$, and $W$ are provided, substituting these into the equation will allow for complete evaluation.

Evaluate the second equation The equation is: $$ Nu = 135 G_{max} + G_{min} R + \Sigma 13 \psi_i Q_i $$ This equation relates Nusselt number ($Nu$) with other parameters. If you have specific values for $G_{max}$, $G_{min}$, and $\psi_i$, substitute them to calculate $Nu$.

Combine and Solve the equations If required, equate the expressions derived from the isolated variables to find relationships among them, or check for consistency in the results obtained.
The final solution is contingent upon substituting the specific values for the parameters involved. Therefore, without numeric values, the expression for $Q_2$ would remain:
$$ Q_2 = Ns  R  pp  G_0  W $$
