Which option do you want? If you choose 1, 2, or 3, tell me whether you prefer more conceptual focus, mathematical derivations, or applied problem-solving.
$$ Ra_D = \fracg \beta (T_s - T_\infty) D^3\nu^2 Pr $$ $$ Ra_D = \frac(9.81)(0.00279)(150 - 20)(0.5)^3(2.14 \times 10^-5)^2 (0.705) $$ $$ Ra_D \approx 1.55 \times 10^9 $$ Which option do you want
Gr = (ρ^2 * g * β * (T_s - T_∞) * L^3) / μ^2 = (1.06^2 * 9.81 * (1/333) * (100 - 20) * 2^3) / (2.03 × 10^(-5))^2 = 5.26 × 10^10 Which option do you want
