A four cylinder, four-stroke, spark ignition engine has a compression ratio of 10 and runs at 2400 rpm. Each cylinder has a bore of 7.6 cm and each piston has a stroke of 9.8 cm. The processes within each cylinder are modeled as an air-standard Otto cycle. At the beginning of the compression process (state 1), the air is at 290 K and 80 kPa. The combustion adds 1100 kJ/kg to the air. Determine:

Ahouse has the following electrical appliance usage (1) single 40w lamp used for 4 hours per day (2) single 60w fan used for 12 hours per day (3) single 200w refrigerator that runs 24 hours per day with compressor run 12 hours and off 12 hours find the solar power inverter size in watt with correction factor of 1.25.

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?
