This is another safety-related problem. It is concerned with the leakage of a gas from a high pressure storage tank. A cylinder of inside diameter 0.63m and height 3.3m is used to store compressed nitrogen. The nitrogen in the vessel is maintained at a constant temperature of 25degree C . Initially, the pressure inside the vessel is 785 kPa . A small hole is formed in the side of the vessel due to corrosion, and the gas stalls leaking out at a constant flow rate of 0.22kg/h. Calculate the pressure in the vessel at the end of nine hours. You must use good judgment m determining the number of significant figures to use in taking the round numbers given in the problem statement and evaluating results from them.
