A cost-effective data acquisition instrumentation for measurement of base pressure and wall pressure in suddenly expanded flow through ducts

Internal flow experimental studies such as sudden expansion in ducts have been reported in the literature. However, the methodology of arriving at the results is not discussed elaborately with the accent on the cost involved and time spent in acquiring the data. This paper explains in detail about t...
