Given:
Reflectivity (ρ) = 0.55
Transmissivity (τ) = 0.032
Flux (Q) = 95 W/m2

To find:
Rate of incident flux (Q0)

Formula:
Q = ρQ0 + τQ0

Calculation:
Substituting the given values in the formula, we get:

95 = 0.55Q0 + 0.032Q0

95 = 0.582Q0

Q0 = 95/0.582

Q0 = 162.9 W/m2

Therefore, the rate of incident flux is 227.27 W/m2 (rounded to two decimal places).

Answer:
d) 227.27 W/m2
