Ehe exhaust heat of around 600oc is used in a heat recovery process to generate electricity through a steam turbine, with a low temperature (after the condenser) of around 40oc. given the utilization efficiency of 0.45 applies to the carnot efficiency for this second conversion process, what is the overall process efficiency, using the realistic efficiency of 0.4 for the gas turbine based process (combined cycles)?

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line

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.
