This one about MP3 players Justin play a 3 min song over and over zak listens to a 5 min sound over and over if they start listening at the same time how long Befor the songs end at the same time

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

The thermal expansion or contraction of a given metal is a function of the f a)-density b)-initial temperature c)- temperature difference d)- linear coefficient of thermal expansion e)- final temperature f)- original length
