/s and density
of 1000 kg/m3
. Using the Buckingham Pi Theorem:
f) Calculate the Reynolds number.
g) Find the velocity required to give the same Reynolds number when the same pipe is transporting
air.
h) Obtain the ratio of pressure drops in the same length of pipe for both cases.
i) Reflect on the case studies provided—Food Processing Industry, Chemical Manufacturing, and Water
Treatment Facilities. Evaluate how the dimensional analysis using the Buckingham Pi
Theorem applies to these scenarios and discuss the specific challenges encountered, such
as variable fluid properties and complex fluid dynamics which are not always captured by the
theorem. Offer practical recommendations for engineers to tailor dimensional analysis
techniques to the unique requirements of each case study scenario, optimizing design and
operational efficiency.
