4.某實驗以1:20的縮小模型測試船體受水流之阻力，當模型速度為2.8m/s時測得阻力為25N，試求原型的速度與阻力為多少？忽略黏滯效應，並假設模型與原型採用相同流體。（25分）

4. What are the major differences (assumptions, terms in the equation) between the Bernoulli equation and the energy equation derived from the Reynolds transport theorem? Express the difference in their governing equation mathematically and explain its physical meanings.
