Answer:
Explanation:
The mass inside the rigid tank before the high pressure stream enters is:
The final mass inside the rigid tank is:
The supplied air mass is:
The air inside a chamber at T[infinity],i = 50 °C is heated convectively with hᵢ= 20 W/m² K by a 200-mm-thick wall having a ther
mal conductivity of 4 W/m K and a uniform heat generation of 1000 W/m³. To prevent any heat generated within the wall from being lost to the outside of the chamber at T[infinity],0 = 25 degree C with h₀ = 5 W/m² K, a very thin electrical strip heater is placed on the outer wall to provide a uniform heat flux, q₀ⁿ.
(a) Sketch the temperature distribution in the wall on T - x coordinates for the condition where no heat generated within the wall is lost to the outside of the chamber.
(b) What are the temperatures at the wall boundaries, T(0) and T(L), for the conditions of part (a)?

Explanation:
In the Armstrong method of FM generation, the phase of the carrier is directly modulated in the combing network through summation, generating indirect frequency modulation.
Very high frequency stability is achieved through Armstrong method since the crystal oscillator is used as carrier frequency generator.
