Mechanisms of heat transfer

Heat transfer is an essential discipline in thermal engineering that deals with the transfer, conversion, usability, and creation of heat or thermal energy. Transfer of heat occurs through various mechanisms like conduction, convection, radiation, and change of phases. All these mechanisms have distinct characteristics, but these mechanisms can simultaneously occur in an identical system.

The 1st law of thermodynamics is ΔU = Q –W. Use this statement of the 1st law to show (mathematically) its equivalent statement: “Total energy of the universe is constant”. Here, the universe can be defined as: system + surroundings (everything but the system –everything outside the system). (Hint: this can be shown by two ways-you may either treat system and surroundings as two systems next to each other, or you may treat system + surroundings (universe) as one system.)
Conduction Heat Transfer X material (a) material (b) . both (a) and (b) have the same thermal conductivity the temperature distribution is independent of thermal conductivity it's not that simple 9. Fin efficiency is defined as: • tanh (mL) (hP/k Ac)1/2 (heat transfer with fin) / (heat transfer without fin) (actual heat transfer through fin) / (heat transfer assuming all fin is at T = Tb) (Tx=L-Tf)/(Tb-Tf) 10. For an infinite fin, the temperature distribution is given by: (T-Tf)/(Tb-Tf)= e-mx. The heat flow through the fin is therefore given by: k (Tb-Tf)/L ● zero, because the fin is infinite ● infinite because the fin is infinite ● (Tb-Tf) (hP/k Ac)1/2 ● (Tb – Tf) (h P / k Ac)1/2 tanh (mL) 11.

Assume the following: ●In a light water reactor, approximately 1.0kg of spent nuclear fuel is produced for every50. megawatt-days (MWd) of thermal energy input. ●For the purposes of this analysis, assume the spent nuclear fuel produced is 1.8% Pu-240by mass. Pu-240 has a half-life of 6,430 years. ●The thermal efficiency of the power plant is 38% ●Use equation for radioactive decay: Qt= Q0^e-kt where: ○Qt = quantity of radioactive material at time t ○Q0 = original quantity of radioactive material ○k = the decay constant ○t = time interval in years ○The decay constant k is defined by the relation: Half life = ln(2)/k Diablo Canyon stores 95% of its spent nuclear fuel onsite. ii) How many metric tons of Pu-240 in the spent fuel will still be onsite in that year?
