Consider a thin plate of 30cm by 30cm is standing vertically in air. One side of the plate is insulated. The plate surface temperature is 700C. The room air temperature where the plate is located is 200C. Determine:(a) Is the flow over the plate laminaror turbulent

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.

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