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.

Question 63 – Autocad computer program is used to draw a pipe that is used to transport natural gases for processing. Actual length of the pipe is 10 metres. The pipe has cross sectional area of circle in shape with measured circumference of s = 3 metres. (a) If 10 units are used to represent the actual length of the pipe in computerised engineering drawing, find the diameter of the pipe, d that will be shown in the engineering drawing. (b) If one unit in the program equals to 1 centimetre, find the scale used in the computer program.

CHEMICAL ENERGY BALANCE - EXAMPLE 11.3 : 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.

ACCOUNTING AND FINANCIAL ENGINEERING - EXAMPLE 34.19 : In the purchase of a unit of engineering office, a loan has been made to a bank with the following details : Term N = 30 years; interest rate R = 8.07 % / year; security : primary residence; present value pv = $450000; salary = $75000 / year or $56000 / year after tax. (a) Let the discounted present value PV = [ 1 - 1 / (1 + r) ^ n ] / r for arrears, where r = interest rate of discount, n = number of payment, ^ = symbol for power. If the loan repayment was made monthly : (i) calculate the value of r where r = R / k and R is in decimal value; (ii) find the value of n where n = kN; (iii) estimate the value of k where k = number of repayment per year; (iv) calculate the value of PV based on the formula of discounted present value. (b) Calculate the monthly repayment of the loan, MR based on the following formula : pv = PV x MR. (c) Find the percentage of salary remains after paying the loan every month.
