Technical papers were invited, for Issue # EE
03. We received 11 papers.
"Issue # EE 03:
Measuring the temperature of a liquid or steam flowing inside
a pipe is not an easy task if there is no temperature sensor
installed
in the pipe. Can you think about a solution to measure the temperature
in a non-intrusive way with a reasonable accuracy? Submit your
ideas."
None of the papers was excellent, but two from
Arvind Rastogi and Suresh Srivastava are close to reality. Arvind
Rastogi rightly points out that, it is pretty simple with fluids
flowing in metal pipes. However, the claim that the pipe outer
surface assumes the same temperature as that of the fluid inside
is wrong, as Suresh Srivastava shares. Nevertheless, this practical
approach is followed over the world. Normally depending on the
measurement set-up, engineers add 1o C to 3o C to the measured
value. However if there is scale inside the metal tube or conductivity
of the tube is low, the error is higher.
The mathematical approach of Suresh Srivastava,
explains how to calculate the temperature correctly, based on
the measurement of the outer surface temperature and thermodynamic
as well as physical assumptions of fluid. His paper properly explains
the logic behind, what Mr. Arvind Rastogi has experienced in his
field work. Both papers together are the solutions. Therefore,
we award Rs 5,000 to each of the papers. We are looking for a
simple software similar to a pop up calculator that could, based
on Mr. Suresh Srivastava's contributions, conveniently calculate
the result.
The winners are :
1. Mr. Arvind Rastogi (Rs.
5,000)
2. Mr. Suresh Srivastava (Rs.
5,000)
Congratulations to winners!
