1. What is the percentage change in the viscosity of water when the water temperature rises from 60 to 1208F?

2. If the ram and auto rack in the previous problem together have a mass of 680 kg, estimate the maximum sinking speed of the ram and rack when gravity and viscous friction are the only forces acting. Assume 2.44 m of the ram engaged.
