Fin effectiveness will be increased more by

The effectiveness of the fin is the dimensionless parameter which can be measured the ratio of the heat transfer from the fin to the heat transfer occupied by the fin without fin attached. No-fin heat transfer rate: )qnf=hAb(Ts−T∞ 1.40 While the heat transfer from the fin can be evaluated from Table 2.1 and 2.2 as: The effectiveness is ε 10. Mark the false statement regarding effectiveness of fin a) A high value of film coefficient adversely affects the fin effectiveness b) Fin effectiveness is improved if the fin is made from a material of low conductivity c) Fin effectiveness is improved by having thin fins d) It can also be improved by having closely spaced fins View Answe In the study of heat transfer, fins are surfaces that extend from an object to increase the rate of heat transfer to or from the environment by increasing convection. The amount of conduction, convection, or radiation of an object determines the amount of heat it transfers Are of section increase along the length d. Better to vary the convection coefficient than the area 101. Fin effectiveness will be increase more by a. Having a higher value of convection coefficient b. Higher sectional area c. Higher thermal conductivity d. Longer circumference 102

Therefore, the fin effectiveness can be determined easily when the fin efficiency is known, or vice versa. The rate of heat transfer from a sufficiently long fin or uniform cross section under steady conditions is given by Equation 3.34. Substituting this relation into Equation 3.40, the effectiveness of such a long fin is determined to b Does the (a) efficiency and (b) effectiveness of a fin increase or decrease as the fin length is increased? Hot air is to be cooled as it flows through the tubes exposed to atmospheric air. Fins are to be attached in order to enhance heat transfer Would you recommend attaching the fins inside or outside the tube Does the (a) efficiency and (b) effectiveness of a fin increase or decrease as the fin length is increased?

Daily dosing of finasteride 5mg tablets for up to 4 years reduced serum DHT concentrations by approximately 70%. Circulating levels of testosterone increased by approximately 10 to 20% but remained within the normal physiologic range. Effects on hair regrowth may take up to three months to be seen Since the fin efficiency is inversely proportional to Λ, it can be improved either by increasing k and B, or by decreasing 〈 h 〉 and L. If the average heat transfer coefficient, 〈 h 〉, is increased due to an increase in the air velocity past the fin, the fin efficiency decreases Effectiveness of Fins - MCQs with Answers 1.

SinceA fin =PL for fins with constant cross section. Equation 3.38 can also be used for fins subjected to convection provided that the fin length L is replaced by the corrected length L c.. Fin efficiency relations are developed for fins of various profiles and are plotted in Figure. 3.10 for fins on a plain surface and in Figure 3.11 for circular fins of constant thickness transfer from surfaces. Typically, the fin material has a high thermal conductivity. The fin is exposed to a flowing fluid, which cools or heats it, with the high thermal conductivity allowing increased heat being conducted from the wall through the fin. Th Efficiency of a fin is defined as the ratio of heat transfer with fin to the heat transfer from the fin when the entire fin surface is maintained at base temperature. Efficiency can't be greater than 1 (100%). This is true always when we talk abou.. BACKGROUND Fins are the extended surfaces that are used to raise the heat transfer rate by means of an increase in convection to or from the environment. The fins broaden the surface area and thus provides an economical and efficient solution of heat transfer problems in both natural and forced convection

Fin effectiveness Fin effectiveness is the ratio of heat transfer from the fin to the heat transfer if the fin wasn't existing. In other words, this quantity tells us how much extra heat is being transferred by the fin. The desire is to have this ration as large as possible while keeping the additional cost of adding the fins as low as possible However, since FIN 48 does require more information to be disclosed about uncertain tax positions than was the case before FIN 48 was issued, it is possible that reopenings will occur more frequently because of the potentially increased availability of information warranting reopening What is effectiveness of fin? - Published on 12 Aug 15. a. the ratio of actual heat transferred from fin area to the heat which would be transferred if entire fin area was at base temperature What is the difference between the fin effectiveness and the fin efficiency? Answer: The fin efficiency is defined as the ratio of actual heat transfer rate from the fin to the ideal heat transfer rate from the fin if the entire fin were at base temperature, and its value is between 0 and 1 economics can make financial education more effective.
