An air-conditioning system delivers moist air to a classroom through a duct. a fan within the insulated duct delivers moist air at the duct exit at 22°c, 60% relative humidity, and a volumetric flow rate of 0.5 m3/s. at steady state, the power input to the fan is 1.3kw. using the psychrometric chart provided (figure 5), determine the temperature and relative humidity at the duct inlet.

Condition monitoring is a major component of. (clo4) a)- predictive maintenance. b)-preventive maintenance c)-proactive maintenance d)-reactive maintenance.

Avolume of 2.65 m3 of air in a rigid, insulated container fitted with a paddle wheel is initially at 264 k, 5.6 bar. the air receives 432 kj by work from the paddle wheel. assuming the ideal gas model with cv = 0.71 kj/kg • k, determine for the air the amount of entropy produced, in kj/k

Describe one experiment in which the glass transition temperature and melting temperature of a totally amorphous thermoplastic material can be determined. show the relevant experimental results in a diagram which should be properly annotated with the two temperatures clearly marked. what is likely to happen to the curve in the diagram if the amorphous polymer is replaced by a thermosetting type?
