A manometer that containing mercury under water measures the pressure differential over instrument, so a venturi meter is placed horizontal and have a throat diameter 20mm is set in a 75mm ID pipe line. At 15oC water is flowing through the pipeline. When the manometer reading is 500mm, what is the flow rate in lit/hr. If 12% of the differential is permanently lost, what is the power consumption of the meter

Plot schematically the tensile stress versus strain curves for a typical thermoplastic material at a temperature below its glass transition temperature (tg and at a temperature above its tg, respectively. do the same for a typical thermosetting material. list in a table any differences or similarities between the two materials at t> tg and t < tg, respectively, and relate them to the structures of the two types of polymers
