1.The dynamic viscosity of water at 20°C is 1.00 x 10-3 N-s/m2, and the viscosity at 40°C is 6.53 x 10-4 N-s/m2. Estimate the viscosity at 30°C.

2.Water in a hydraulic press is subjected to a pressure of 4500 psia at 68 degrees F. If the initial pressure is 15 psia, approximately what will be the percentage decrease in specific volume?

3.The pascal (Pa) is actually a very small unit of pressure. Tho show this convert 1Pa= 1 N/m^2 to lb/ft^2. Atmospheric pressure at sea level is 14.7 lb/in^2. how many pascal is this?

4.A scientist plans to build a water barometer. When the atmospheric pressure is 990 mb abs and the water temperature is 70 degrees Celsius, what would you expect the barometer reading (water rise) to be?
