Consider an ideal Brayton cycle executed between the pressure limits of 1,130 kPa and 100 kPa and temperature limits of 293 K and 1,049 K with air as the working fluid. Determine the turbine work output (kJ/kg) of the cycle (to the nearest unit value) using cold-air-standard assumptions.

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.

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above
