Question
**Problem Statement:** A flat-bottomed barge, which is 20 meters long and 10 meters wide, is to be pushed up a river at a speed of 4 km/h. Estimate the power required to overcome the skin friction at the bottom surface of the barge if the water temperature is 10°C. **Analysis:** This problem involves calculating the power needed to overcome the resistance due to skin friction when a barge moves through water. Key parameters include the dimensions of the barge, its speed, and the temperature of the water, which influences water viscosity.
