Water vapor enters a turbine operating at steady state at 480°C, 90 bar, with a velocity of 300 m/s, and expands adiabatically to the exit, where it is saturated vapor at 12 bar, with a velocity of 145 m/s. The exit diameter is 0.35 m. Determine the power developed by the turbine, in kW.

Afluid flows with a velocity field given by v=(x/t)i.. determine the local and convective accelerations when x=3 and t=1.

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false
