Bioengineering and biomedical engineering merge the disciplines of engineering, biology, and medicine to create techniques and devices that are based on an understanding of living systems and serve the objective of improving the quality of human and animal life.
Weight of 1 US Gallon of water = approx. 8.35 lb (about 3.785 kg). Weight of 1 Imperial gallon (i.e. UK measure) of water weighs 10 pounds (4.536 kg) by definition, at a specified temperature and pressure.
Five gallons of fresh water weigh 41.7 pounds, because each gallon of water equals 8.34 pounds. At the boiling point, a gallon of water has a weight of only 7.996 pounds. A cubic foot of room temperature water weighs 62.4 pounds.
