A sine wave is displayed on the oscilloscope. One period (horizontal distance from peak-to-peak) is 2.8 divisions with the Time Base set to 0.2 μS (microseconds) per div.

What is the period of the sine wave?

Air is compressed in the compressor of a turbojet engine. Air enters the compressor at 270 K and 58 kPa and exits the compressor at 465 K and 350 kPa. Take the average specific heat at constant pressure (cp, avg) of air as 1.015 kJ / kg.

The Reynolds number, rhoVD/μ is a very important parameter in fluid mechanics. Determine its value for ethyl alcohol flowing at a velocity of 4 m/s through a 2-in.-diameter pipe.

Work done by a system during a process can be considered as a property of the system. a) True b) False

When the compression process is non-quasi-equilibrium, the molecules before the piston face cannot escape fast enough, forming a high-pressure region in front of the piston. It takes more work to move the piston against this high-pressure region.

hypothetical A-B alloy of composition 40 wt% B-60 wt% A at some temperature is found to consist of mass fractions of 0.66 and 0.34 for the α and β phases, respectively.
