Answer / bharat

temperature inside heat-exchanger changes exponentially so
taking average would give erroneous results. and LMTD is
calculated by considering a small elemental area of heat
exchanger so it gives more accurate temperature difference.

Answer / awkash

Because temperature change in heat exchanger is not linear
in nature so we can not take airthmatic mean here,
physically you can think in the manner like if we inlet
temp. of a pipe is 80 and outlet temp. is 40 then u cannot
say that temp in middle will be 60.
thats why for accurte measurement we take lmtd.

Answer / abina

in heatexchanger temperature changes from point to point along the length so we are calculating Lmtd. ..Bt avg temperature dosnt gv correct value

Answer / anil

LMTD value it gives the correct average temperature without any errors compare to average temperature

QUANTUM BIOLOGY - EXAMPLE 33.6 : The time to maintain quantum coherence in a biological system is t. Let t = k / (MT) where k = constant, M = mass, T = temperature. For living farm animals, normal rectal temperatures ranges for pig and goat are 38.7 - 39.8 and 38.5 - 39.7 in degree Celsius respectively. Let a pig has a mass of 100 kg and a goat has a mass of 300 pounds. (a) Find the mass of goat in the unit of kilogram, when 1 pound = 0.4536 kg. (b) Find t (p) / t (g) for living animals when t (p) = t for pig and t (g) = t for goat. (c) State the assumption of your calculation in question (b).
