4PRACTICE PROBLEM
A highly energetic object with a mass of 2 kg passes through a horizontal water pipeline containing water at 30 °C. The object's initial speed is 3 km/s, and it loses all its kinetic energy through viscous drag in the water. If 25% of the lost kinetic energy goes to boiling the pipeline water while the rest is lost as turbulence, how much water will evaporate due to viscous drag?
