Answer / sangilisaravanan
FIN TUBES INCREASES THE SURFACE AREA OF HEATING.
SO FOR THE REQUIRED QUANTITY OF HEAT TRANSFER THE EXCHANGER
MAY BE DESIGNED SMALL IN COMPARED WITH FINLESS TUBE
EXCHANGER

Fin tubes are usually used for cooling.As we see in
automobile engines constructed with fins.

Answer / anshuman
it depends on the kind of liquid to be heated and steam
requirment if high heat transfer is required with low
cosumpsion of steam we can use fin tubes

Answer / jagadesh
it is not required to heat up liquid in fin tubes by steam
because liuid has to pass trhough tube side. so if
temperature difference is more steam will undergoes
condensation and will lead high pressure drop and less heat
transfer.

Answer / dp
It depends on the htc values on the shell side. If HTC on
the shell side is higher than the tube side adding tubes
wont make much difference in terms of total heat transfer.
If the HTC value on the tube side is higher than the shell
side, adding fins will enhance the total heat transfer. For
suppose if steam is flowing on the tube side and its phase
changes during the process its good to provide fins over the
tubes. If it is other way adding fins wont make much
difference except increasing cost of the exchanger.

Answer / ahmedcool
FINS ARE USED TO INCREASE SURFACE AREA,IS LIKELY TO
TRANSFER HEAT FROM HOTTER BODY TO COLDER BODY.FINS ARE NOT
REQUIRED IN CASE OF STEAM HEATING.

Answer / amol deshpande
Yes, fin tubes are necessary. Fin tubes increases the heat surface area and reduces the thickness of shell wall required.

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).
ACCOUNTING AND FINANCIAL ENGINEERING - EXAMPLE 34.29 : An engineering company that produces small biochemical tools applies Installment Sales Method in its accounting. Let A = Installment Sales, B = Cost of Installment Sales, C = Gross Profit, D = Gross Profit Ratio. In year 20X8, let A = $400, B = $250, C = $150. In year 20X9, let A = $450, B = $315, C = $135. If the value of D = 37.5 % in year 20X8 : (a) find the value of D for year 20X9; (b) calculate the realized gross profit = ED / 100, for year 20X8 when the cash collected from sales is E = $100.
