Design two shell programs working on Linux (Ubuntu)
Design a shell script program, 1) reading given only two
integer numbers from command line arguments and computing their
multiplication. If two integer numbers are not given, print “Wrong
Input” on your screen. Note that, the number of arguments is known
when the script runs.
Take a screenshot showing your shell program and its execution
step.
Design a shell program to remove all the shell programming
files ending with sh on your...
Design of Shell and Tube Heat Exchanger
Crude oil at 198°C is to be cooled to 39°C. The oil flow-rate is
6.127 kg/s. Cooling water
is available at 29°C and at the rate of 27.127 kg/s. The pressure
drop allowance for each stream
is 100 kN/m2
. Design a suitable shell and tube heat exchanger for this
duty.
The following are the properties of the two streams at the average
temperature:
water
crude oil
density kg/m3

liquid oil is used in the tube side of a shell-and-tube heat
exchanger with two shell passes and four tube passes. water is
heated in the shell side from 10°C to 50°C while the oil is cooled
from 90°C to 60°C. the overall heat transfer coefficient is 53
W/m^2*K. the specific heat of the oil is 2.0 kJ/kg*K. Using the NTU
- effectiveness method, calculate the area of the heat exchanger
for a total energy transfer of 500 kW. what...
A shell and tube type of heat exchanger with one shell pass and
two tube passes will be designed to provide the given heat transfer
rate Q(kW) to cool hot water by using cold river water . The hot
water flows through the shell and the cold water flows through the
tubes. The inlet and outlet temperatures of the hot water and the
cold water are given as Thi, The and Tci, Tce in degrees Celcius.

A shell-and-tube heat exchanger with two tube passes and baffled
single shell pass is used as oil cooler. Cooling water at 20°C
flows through the tubes at a flow rate of 4.082 kg/s.
Engine oil enters the shell side at a flow rate of 10
kg/s. The inlet and outlet temperatures of oil are 90°C
and 60°C, respectively. The overall heat transfer coefficient based
on the outside tube area (Uo) is 262
W/m2⋅K. The specific heats of water and oil...

1. Shell momentum balance for flow between parallel plates. A
fluid of constant density is flowing in laminar at steady state in
the horizontal x direction between two flat and parallel plates.
The distance between the two plates in the vertical y direction is
2yo. a) Derive the equations for momentum flux, velocity profile,
average velocity, volumetric flow rate and the force exerted by the
fluid on the plate. b) Show the shear stress and velocity profiles
on the figure.
A shell-and-tube heat exchanger is to used to heat water (in the
tube side) from 30 deg C to 40 deg C at a mass flow rate of 4 kg/s.
The fluid used for heating (shell side) is water entering at 90 deg
C with a mass flow rate of 2 kg/s. A 1-2 STHE is used and the
overall heat transfer coefficient based on the inside area is 1390
W/m2-K. The tubes are 1.875 in diameter (inside) and require...
