5. Ammonia is stored in a tank at room temperature and a pressure of 2.5 x10° pa. A vent line with a diameter of 0.0854m broke out letting ammonia to be released out of the plant to the surrounding residential area. Saturated vapour pressure of ammonia at room temperature is 0.968 x106 pa and its density is 603 kg/m3. a. Determine the mass flow rate through the broken line assuming equilibrium conditions. b. If there is a residential area 1.5 kilometre away from this plant with wind speed in the area being 3.5 m/s and dispersion coefficients being ox = 5m, oy=6m and oz = 3m, how much time does it take for the ammonia cloud to reach the residential area and what will be the concentration of the ammonia when it reaches the residential area, will there be enough time for action.
