Oil vs. Water Density. Pure water is the reference point, so it has a specific gravity of 1.000. Salt is more dense than water, so seawater has a specific gravity of about 1.025, depending on the location. Crude oil density varies by location; light crude, such as that from Texas, measures at about 0.876, and heavier oils check in at 0.918.
Symptoms of severe or chronic dehydration are extreme thirst, confusion, little or no urination, sunken eyes, very dry mouth, dry skin that lacks elasticity, low blood pressure, rapid heartbeat, rapid breathing and even delirium or unconsciousness. If not treated timely, dehydration can lead to several complications.
10 Dehydration Symptoms. Dehydration (hypohydration) is a condition, wherein the loss of fluids (water) exceeds fluid intake. Even a minor change in the fluid concentrations can result in dehydration. It is, therefore, important to top-up on H2O as you lose it, else you will become chronically dehydrated (which can cause death). Some of the common causes of dehydration are fever and immense sweating; intense workout, primarily in summers; and diarrhea.
