The enthalpy of a real gas, in general, depends on the pressure as well as on the temperature. devise a way to evaluate the change in enthalpy of a real gas associated with a change of state from (t1,p1) to (t2,p2). describe in a t-s diagram how you would find enthalpy changes.

What precautions should you take to prevent injuries when dealing with heavy loads?

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
