A cylindrical tank filled to a height of 25 feet with tribromoethylene has been pressurized to 3 atmospheres (Psurface= 3 atmospheres). The total pressure at the bottom of the tank is 5 atmospheres. Determine the density of tribromoethylene in units of kilogrms per cubic meter.

Explanation:

Given:

height of the given liquid in the tank,

pressure at the surface of the liquid,

pressure at the bottom of the liquid,

So the pressure due to height of the liquid column:

Now as we know that the pressure due to the height of liquid column is given as:

where:

density of the liquid

acceleration due to gravity
