The volume flowrate of a liquid in a 300 mm diameter pipe is 0.06 m3/s. the liquid has viscosity of 1.783 x10-5 pas and relative density of 0.7. the equivalent surface roughness of the pipe is 0.6 mm. determine, (a). re and state if the flow is turbulent (b). the friction factor f. (c). the pressure drop over a 100m horizontal length of pipe.

Two technicians are discussing the intake air temperature (iat) sensor. technician a says that the computer uses the iat sensor as a backup to the engine coolant temperature (ect) sensor. technician b says that the powertrain control module (pcm) will subtract the calculated amount of fuel if the air measures hot. who is correct

Determine (a) the maximum thermal efficiency of reversible power cycles operating between a hot reservoir at 1000°c and a cold reservoir at 200°c and (b) the maximum cops for reversible refrigeration and heat pump cycies, respectively, between 28°c and 14°c.

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
