Hey fiyin, good to see you again. Here's how to calculate the rate of energy transfer by conduction: Step 1: Identify the given values. Thermal conductivity of water (k) = 0.6071 \, W m^-1 K^-1 Surface area (A) = 620 \, m^2 Depth (L) = 1.5 \, m Surface temperature (T_surface) = 25^ Bottom temperature (T_bottom) = 15^ Step 2: Calculate the temperature difference ( T). The temperature difference is the absolute difference between the two temperatures. T = T_surface - T_bottom T = 25^ - 15^ T = 10^ Since a change of 1^ is equal to a change of 1 \, K, T = 10 \, K. Step 3: Use the formula for the rate of heat transfer by conduction. The formula for the rate of heat transfer (P) is: P = k A ( T)/(L) Step 4: Substitute the values and calculate P. P = (0.6071 \, W m^-1 K^-1) × (620 \, m^2) × 10 \, K1.5 \, m P = 0.6071 × 620 × (10)/(1.5) P = 0.6071 × 620 × 6.666... P ≈ 2509.35 \, W Step 5: Convert the answer to kilowatts (kW) and select the correct option. To convert Watts to kilowatts, divide by 1000: P = 2509.35 \, W1000 P ≈ 2.509 \, kW Rounding to one decimal place, P ≈ 2.5 \, kW. Comparing this to the given options: A) 250 \, W B) 2.5 \, kW C) 3.0 \, kW D) 300 \, W The calculated rate matches option B. The final answer is B. Send me the next one 📸
