Carbon dioxide (co2) gas enters a turbine operating at steady state at 50 bar, 500 k with a velocity of 50 m/s. the inlet area is 0.02 m2 . at the exit, the pressure is 20 bar, the temperature is 440 k, and the velocity is 10 m/s. the power developed by the turbine is 3 mw, and heat transfer occurs across a portion of the surface where the average temperature is 462 k. assume ideal gas behavior for the carbon dioxide and neglect the effect of gravity. let t0 = 298 k, p0 = 1 bar
determine the rate of heat transfer, in kw.

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

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
