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.

Question 31 – For liquid benzene, the CP constants are : a = 129440, b = - 169.5, c = 0.64781. Reference temperature is 298 K. The temperature of benzene is 60 degree Celsius. Calculate the enthalpy of benzene by using the formula H = a (DT) + (b/2) (T^2 – TREF^2) + (c/3) (T^3 – TREF^3) where ^ is power, DT is temperature difference with TREF = 298 K. H is in J / kmol. DT = T – TREF.

MY generator water cooler inlet line height - 11 mtr inlet water line height - 7 mtr water come into the line from overhead tank, O/H tank height - 20 mtr the first tapping in the inlet line is 2" line which down to 4 mtr level plateform., second tapping in inlet water line goes to a pump 6" line installed at 4 mtr level plateform, pump capacity 200m3/hr, head- 30 mtr, hp-40. the outlet of pump of 6" water line connected to a header of 6 mtr long of 6" line, on this header the six tapping are connected, 4 nos. 3" line goes to 11 mtr height water cooler the pressure of the line is 0.15 to 0.25 kg/cm2, 2" and 4" pipe line connected to a cooler at 4 mtrlevel plateform. my question is, at 11 mtr height level the quantity of water and flow is not sufficient for my cooler, the temp. of cooler is rises much more. you are requested to suggest the modification of pipe line/ pump for take more water flow and pressure (desired pressure is 1 kg/cm2)
