Air enters a diffuser operating at steady state at 540°r, 15 lbf/in.2, with a velocity of 600 ft/s, and exits with a velocity of 60 ft/s. the ratio of the exit area to the inlet area is 10. assuming the ideal gas model for the air and ignoring heat transfer, determine the temperature, in °r, and pressure, in lbf/in.2, at the exit.

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

On a average work day more than work place firs are reorted

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.
