Exhaust combustion products flow through a concentric square composite (k = 0.85 W/m·K) channel of unit length. The edge of the outer square is b = 6 cm and the inner edge is a = 2 cm. The duct is placed in a corridor such that the air temperature is 300 K with a convection coefficient of 75 W/m2·K. The exhaust gases maintain a uniform inner channel surface temperature of 500 K. a) Using numerical methods, find the temperature distribution...

a) By direct substitution determine which of the following functions satisfy the wave equation. 1. g(x, t) = Acos(kx − t) where A, k, are positive constants. 2. h(x, t) = Ae where A, k, are positive constants. 3. p(x, t) = Asinh(kx − t) where A, k, are positive constants. 4. q(x, t) = Ae where A, a, are positive constants. 5. An arbitrary function: f(x, t) = f(kx−t) where k and are positive constants. (Hint: Be careful with...

NE Steel tubes (k =35 W/m2.K) of 400-mm inner diameter and 30-mm wall thickness are used to route superheated steam from the boller to the turbine in a power plant. Safety and economic concerns make it practical to add a 200-mm layer of Insulation (k =0.1 W/mK) to each tube, which is wrapped in a thin sheet of aluminum with an emissivity e =0.15. The air (with a convective coefficient h =5 W/m2K) and wail temperatures of the plant are...

Consider the imaginary element Nn with at least two electrons in all its shells. The ionization energies of those shells are for K, 10.0 KeV, for L, 3 KeV and for M, 1 KeV. Which Auger electrons will be emitted 20 KeV, 5 KeV or 2 KeV incident electron energies? Imagine the sample is struck by a 2 KeV photon. From what shells can photoelectrons be emitted and at what energies? Imagine the same experiment but with the M ionization...
