1. The specific weight of a certain liquid is 85.3 lb/ft3. Determine its density and specific gravity.
2. An open, rigid-walled, cylindrical tank contains 4 ft3 of water at 40°F Over a 24-hour period of time the water temperature varies from 40 to 90°F Make use of the data in Appendix B to determine how much the volume of water will change. For a tank diameter of 2 ft, would the corresponding change in water depth be very noticeable? Explain.
