These side effects included: 1  Abdominal (stomach) pain. 2  Fever. 3  Infections. 4  Pain. 5  Blood infection (sepsis) 6  Diarrhea. 7  Vomiting. 8  A sore throat. 9  Respiratory tract infections, such as the common cold. 10  High blood pressure (hypertension) 11  Low red blood cell count. 12  Low white blood cell count.
If the water were unconstrained the resuting ice has SG ~ 0.915, so volume change on freezing = 1/0.915 - 1 = 0.092. According to my data, the bulk modulus of water = 2*10 4 bar. Making the assumption that the bulk modulus of ice is about the same, pressure rise =. 0.092*2*10 4 = 1840 bar.
The pressure at sea level is 1 atmosphere by definition. If the water surface you are referring to is at sea level then clearly the pressure at the water surface is 1 atmosphere. If the water surface happens to be a body of water at a higher elevation (on top of a mountain) then the atmospheric pressure at the surface would be lower. To experience the pressure of 2 atmospheres you would need to dive 10.3 m underwater or 33.79 feet at sea level. Zero. One atmosphere exists at the surface.
