Pressure gauge at the top of a vertical oil well registers 140 bars. the oil well is 6000 m deep and filled with natural gas down to a depth of 4700 m and filled with oil (density=700 kg/m3) the rest of the way to the bottom of the well at 15°c. the compressibility factor z=0.80 for natural gas and its molecular weight is 18.9.
determine the pressure at (a) the natural gas-oil interface and at (b) the bottom of the well at 15°c.

In november 1987, a massive iceberg broke loose from the antartic ice mass and floated free in the ocean. the chunk of ice was estimated to be 98 mi long, 25 mi wide, and 750 ft thick. a typical backyard swimming pool contains about 24,000 gallons of water. how many of these pools could you fill from the water in this iceberg? (assume the iceberg is a rectangular solid of the above dimensions and consists of water only). express answer in scientific notation.
