R134a enters an adiabatic compressor as a saturated vapor with a pressure of 120 kPa. The volumetric flow rate entering the compressor is 0.3 m3/min. The compressor isentropic efficiency is 80%. The exit pressure is 1 MPa. Find the temperature of the refrigerant at the exit and the power required to run the compressor. (

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.

Wiy doeres rere okhn a pump whon working betwon the same pressure range?

Plan an experiment to measure the surface tension of a liquid similar to water. if necessary, review the ncfmf video surface tension for ideas. which method would be most suitable for use in an undergraduate laboratory? what experimental precision could be expected?
