The porosity of a packed bed can be decreased by vibrat- ing the containment vessel as the vessel is filled with the particles. The vibration promotes particle settling.
(a) Consider the air chilling process of Problem 7.110a. Determine the outlet air temperature To and mass rate at which the PCM is melted for s = 0.30. Assume the total mass of PCM and the mass flow rate of air are unchanged. The length of the containment vessel Lv is decreased to compen- sate for the reduced porosity.
(b) Determine To and the PCM melting rate for the case where the diameter of the containment vessel Dv is decreased to compensate for the reduced porosity. Which containment vessel configuration is preferred?

1kg of a gas in a piston-cylinder assembly undergoes a Carnot power cycle for which the isothermal expansion occurs at 800 K. The change in specific entropy of the gas during the isothermal compression, which occurs at 400 K is -25 kJ/kg. K.
Estimate the concentration (in ppm) and the mass emission rate of NOx (in kg/hr, expressed as NO) if a coal containing 1.5% nitrogen is combusted at 1400 K using an air/fuel ratio that is 1.5 times the stoichiometric ratio.
