The ammonia gas (mw = 17 kg/kgmol) at 40 oC and 3 atm was transported at flowrate of 5 kg/h by an insulated pipeline having the total thickness of 2.0×10-3 m. The pressure and temperature of the ammonia gas suddenly drop to ambient temperature and pressure of 25 oC and 1 atm. A thorough investigation showed that the ammonia gas leaked to surrounding atmosphere through a pipeline wall cracking hole having an equivalent diameter of 3 mm.

a) State all the assumptions. Determine the mass rate of ammonia gas lost to surrounding atmosphere as well as the mass contamination rate of ammonia gas in the insulated pipeline by air (mw = 28.97 kg/kgmol).

b) Determine the mole fraction air in the pipeline. If repairing the pipeline required 5 hours, how much ammonia gas was lost from the incident.

Given: Ammonia-air diffusivity, DAB at 298.0 K is 2.8×10-5 m2 /s. The ammonia gas and air at those conditions could be assumed obeyed an ideal gas law. The universal gas constant, R is 8.205×10-2 m3 atm/kmol.K.

1.7 kg/s NH3 and 20 m3/s air at 25 oC and 1 atm are fed into a reactor in which the ammonia is completely consumed. The product gas emerges at 300 oC. Calculate the rate at which heat must be transferred to or from the reactor, assuming operation at approximately 1 atm. You must show full systematic working. The standard heat of reaction for the oxidation of ammonia is given below: 4 NH3(g) + 5 O2(g) ? 4 NO(g) +...

17. At a certain gas station 40% of the customers request regular gas, 35% request unleaded gas, and 25% request premium gas. Of those customers requesting regular gas, only 30% fill their tanks all the way up, while the remaining 70% only fill up part of their tank. Of those customers requesting unleaded gas, 60% fill their tanks all the way up, while of those requesting premium, 50% fill their tanks all the way up. If the next customer does...
