A ship lying in the mouth of a river in water of density 1030kg per cu.m and the displacement is 12 000 tons. The ship is to proceed up river and berth to dock at water with density 1008 kg per cu.m with the same draft. what is its new displacement, in tons? 256.31 tons 11650 11 744 256 000
The clear plastic bottles used for carbonated beverages (sometimes also called “soda,” “pop,” or “soda pop”) are made from poly(ethylene terephthalate) (PET). The “fizz” in pop results from dissolved carbon dioxide (CO2); because PET is permeable to CO2, pop stored in PET bottles will eventually go “flat” (i.e., lose its fizz). A 20-oz. bottle of pop has a CO2 pressure of about 485 kPa inside the bottle, and the CO2 pressure outside the bottle is 0.6 kPa. The Permeability Constant of the PET bottle is 0.23 x 10^-13 cm3@STP.cm/cm2.s.Pa. Note: assume that each bottle has a surface area of 500 cm2 and a wall thickness of 0.07 cm. If the bottle must lose 750 (cm3 STP) of CO2 before the pop tastes flat, what is the shelf life in days for a bottle of pop? Round your answer to 0 decimal places.

The diameter of ball which is suspended by a rope in atmosphere is 10cm , what is the tension in the rope if the density of ball is 2000kg/m3 10.2 N 13.6 kN 56.4 N 40.5 kN
The clear plastic bottles used for carbonated beverages (sometimes also called “soda,” “pop,” or “soda pop”) are made from poly(ethylene terephthalate) (PET). The “fizz” in pop results from dissolved carbon dioxide (CO2); because PET is permeable to CO2, pop stored in PET bottles will eventually go “flat” (i.e., lose its fizz). A 20-oz. bottle of pop has a CO2 pressure of about 570 kPa inside the bottle, and the CO2 pressure outside the bottle is 7 kPa. Assuming conditions of steady-state, calculate the diffusion flux in cm3 at STP/cm2.s of CO2 through the wall of the bottle. The Permeability Constant of the PET bottle is 0.23 x 10^-13 cm3@STP.cm/cm2.s.Pa. Note: assume that each bottle has a surface area of 500 cm2 and a wall thickness of 0.07 cm. Answer in Scientific Notation example 1.1e-12. Round your answer to 2 significant figures.
Q2/ How much fluid is required to raise the pressure in a thin cylinder of length 3 m, internal diameter 0.7 m, and wall thickness 12mm by 70kN/m*? E = 210GN/m* and v = 0.3 for the material of the cylinder and K = 2.1 GN/m* for the fluid.
Green Arrow is helping clean up some pollution from fracking. He fills a tank with the pollutants the result is a tank filled to a depth of 21.0 cm with brackish water on top of which floats a 56.1 thick layer of crude oil. Assuming that the density of the brackish water is 1.000 g/cm^ 3 and the density of the crude oil is 0.965 g/cm^ 3 what will be the gauge pressure (in kPa) at the bottom of the tank? Explain how you solved the problem involving a fluid-filled tank. Be sure to state what your known and unknown quantities are, what concepts were applied, and what equations were used!
