Answer / sagar mashru

Hot oil should be passed from tube side to prevent the heat
loss and it is desirable from safety point of view.

Answer / hemant jansari

Generally hot fluid should be kept in tube side and cold
fluid sould be kept in shell side for better heat transfer.
But as per operation point of view high corrosive fluid
flow in tubeside for less maintenance. It is depended on
operating condition and cost.

Answer / nameh

hot and cold fluids are not well defined. the most important
criteria for tube side fluid selection is corrosive
potential, scale deposition possibility and maintenance
requirements. upon exact definition of fluids; information,
specially hot fluid, the judgement can be performed.

Answer / gopi

the answer depends on the situation. like for example if i
want to condense the hot liquid then i will pass hot liquid
in tube side and & cold liquid on shell side. and if i want
to heat the fluid then we will pass hot liquid in shell side
& cold liquid in tube side for getting more heat transfer area.

Answer / dabhi mahesh

If hot fluid no phase
change than pass
though tube side
increase heat transfer
area. And hot fuid
phase change than
pass though shell
side,cold fuid transfer
area increased.

Answer / mehul patel

no, cool water is to be pass through tubr side is
desirable, due to ease of maintenance reason and safety
point of view also.

FOOD ENGINEERING - QUESTION 23.3 : (a) In the measurement of the browning (optical density) of fruit juice at 10 day interval, the following pairs of data are obtained with time t in days and browning or optical density (OD) : t = 0, OD = 0.05; t = 10, OD = 0.071; t = 20, OD = 0.089; t = 30, OD = 0.11; t = 40, OD = 0.128; t = 50, OD = 0.149; t = 60, OD = 0.17. (i) By using Excel or other programs, determine if such browning reaction can be characterised by pseudo zero order kinetics, with strong correlations between the data pairs of t and OD. (ii) When OD = 0.24, the shelf life T of such juice is expired. Calculate the value of T. (b) Let food cost percentage = ( food cost / food sales ) x 100. If total food cost of bread and butter are $25, food cost percentage of bread is 50 % and for butter is 50 %, find the total food sales of bread and butter.

MASS TRANSFER - EXAMPLE 4.3 : According to Adolf Eugen Fick (1829 - 1901) : rate of diffusion v increases with less wall thickness t, increased area A and decreased molecular weight of a fluid M. The diffusion constant D decreased with increasing M. (a) By assuming v, t, dP, A, M and D changes proportionally of each other, find the equation of v as a function of t, dP, A and D. (b) The ratio of self diffusion constant D, at T = 273 K and P = 0.1 MPa, for gases B and C are 1.604 : 0.155. If only 2 gases exist in such a system : hydrogen and nitrogen, find the type of gas for B and C with reference to their molecular weights M. (c) By using the equation of kinetic energy 0.5 MV = constant where V = square of v, find the ratio of V for B and V for C, or V(B) / V(C), as a function of M(B) and M(C), where M(B) is molecular weight of B and M(C) the molecular weight of C : Graham's Law of Diffusion.
