Air is expanded isentropically in an adiabatic turbine, to produce 85 kw of power. if the mass flow rate is 0.55 kg/s, and the air at the exit is 500 k and 230 kpa, then what is the temperature and pressure at the inlet of the turbine? (a) the temperature is k. (b) the pressure kpa.

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

Explain the strain-hardening phenomenon on the basis of dislocation - dislocation strain field interactions. also, briefly describe what generally happens to the ductility of a metal that has been strain hardened (i.e. does strain hardening make a metal more ductile or

What is the direction and how to operate the lathe?
