Problem 5 (20 points) Carbon dioxide ($$CO_2$$) enters a steady state compressor at 1 bar and 300 K and is compressed adiabatically to 10 bar, 520 K. $$CO_2$$ is modeled as an ideal non-calorically perfect gas*, and kinetic and potential energy effects are negligible. Determine: a. the work input $$\dot{W}$$, in kJ per kg of $$CO_2$$ flowing. b. the rate of entropy production $$\dot{\sigma}$$, in kJ/K per kg of $$CO_2$$ flowing. c. the isentropic compressor efficiency $$\eta_c$$. d. Sketch (by hand) the compressor process on a T-s diagram. * Use Table A-20 to evaluate the thermodynamic properties of $$CO_2$$.

A string of mass density μ = 7.30 × 10−3 kg/m is stretched horizontally between two fixed supports with a tension T = 1000 N, and two successive standing-wave frequencies are observed at 450 Hz and 540 Hz. There are other standing-wave frequencies lower than 450 Hz and higher than 540 Hz, but no others between. (a) What is the speed of transverse waves on the string? (b) What is the length of the string? (c) What is the frequency of the lowest standing-wave mode (first harmonic)?

A 2.5 m string is clamped at both ends so that standing waves may be set up along its length. Standing waves are found to exist at frequencies of 112 Hz and 140 Hz. The string will not sustain standing waves at any frequency between 112 Hz and 140 Hz but may sustain standing waves at higher or lower frequencies.
