5) A wire resistor of 1 mm diameter is in an ambient with T[infinity] = 33°C and h = 500 W/m2·K. The electrical resistance per unit length of wire is 0.01 Ω/m.

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.
