Arankine cycle utilizes heat from a geothermal source: hence, steam is only available at 550f and 900 psia into the turbine, whose efficiency is 95%. the condenser pressure is 4 psia, the pump efficiency is 82% and there is a 100 psia pressure drop across the boiler. a) determine the enthalpies at the all states b) determine the cycle efficiency

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?
