We have an air flow inside a frictionless duct with heat transfer. At location 1, flow has pressure, p1 = 1 atm., T1 = 288 K and M1 = 0.2. Capture the Rayleigh line between Mach number 0.2 to 4.0 initially by adding heat q in small increments taking the flow to M = 1 at location 2, there after removing heat until you achieve M = 4. Use the differential equations from lecture 7 to get new Mach number, M after adding heat q, then use the newly calculated M in differential equations to compute entropy s and thereafter T. Once you compute M, you can compute ratios like p/p*, T/T* etc.
(1) Plot Rayleigh line (T-s plot) between M = 0.2 to 4.
(2) Plot T0/T0*, p/p*, Ρ/Ρ*, T/T*, u/u*, p0/p0* (keep y axis range 0 - 4)
(3) Find T, when M = 1/sqrt(γ) (i.e. when dT/ds = 0) and M = 1 (i.e. when ds/dT = 0)
(4) Verify that you achieve same T at M = 1, when you hand calculate starting from M1 = 0.2 and M1 = 4 using lecture 6 material and tables in the text.
You can assume s1 = 0 to start with. For air Cp = 1004.5 J/kg.K, γ = 1.4. Using MATLAB solve the ODEs using any method (Euler's Method or RK method). Submit script of your code in the project report.

Torque generated by my legs while using elliptical machine
: Since it is fall, the days are getting shorter so I started running indoors on an elliptical machine. It has a readout that states the number of RPMs of its internal flywheel and how many Watts I am generating while exercising.

Could this method result in the liquefaction of air
: Air expands adiabatically (no heat in, no heat out) from T = 300 K and P = 100 atm to a final pressure of 1 atm. Treat the gas as ideal with Cp/Cv = 1.4, and decide the final temperature. Compare your result to the boiling points of oxygen (90.2 K) a..

Stagnant air over a surface typically decreases the pressure
: Movement of stagnant air over a surface typically decreases the pressure that air exerts on the surface it was in contact with, and higher air velocities usually result in more important pressure drops. This pressure drop from rapidly moving air acro..
