The conventional method of conducting laboratory
experiments in engineering becomes a serious challenge asa result of the
COVID-19 pandemic; the development of a virtual laboratory is considered a
suitable substitute to real laboratory. In this work, a virtual laboratory for
a family of centrifugal pumps has been developed. Cavitation development within
the centrifugal pumps and the pumps performances in pipeline networks were
studied. Negative potential head and high
fluid temperature increased early cavitation incidence, while low fluid
temperature, as well as positive potential head reduced it. The choice of pipe
diameter and its roughness factor played significant roles in the pumps’
performance. The study shows that virtual laboratory represents a good training
environment that enables precise pipeline and pump flow matching.

The current
COVID-19 pandemic, declared as an outbreak of Public Health Emergency of
International Concern by the World Health Organization in January 2020 (Harapana et al., 2020) and identified as a
pandemic in March 2020 (Gennaro et al., 2020)
is posing an enormous threat to the conduct of reallife laboratory experiments.
In combatting the global lockdown
attributed to the COVID-19 pandemic, there is a need to explore new
alternatives to academic delivery, and the virtual class mode is a promising
way forward (Evans et al., 2020; Arora and Srinivasan,
2020). In a recent publication,Salmerón-Manzano
and Manzano-Agugliaro (2018) observed that “bibliographic analysis
confirms that research in virtual laboratories is a very active field, where
scientific productivity has exponentially increased over recent years in tandem
In many
developing countries, the practical experience required by students of science and
engineering to fully understand theoretical aspects of their courses are
inadequate. A pragmatic approach to solving this problem is to develop a computer-simulated
virtual laboratory to complement existing laboratories to improve the
identified problems. While it is
capital-intensive to set up real laboratories that investigate varieties of
flow parameter dependences, a virtual laboratory for flow pipe networks is
simple and cost-effective, particularly in developing countries experiencing
economic challenges. The virtual laboratory makes sure that its resources are
available to each student, unlike in a real laboratory where students form
groups to perform an experiment. Therefore, the objective of this work was to
leverage on he benefits of a virtual laboratory to develop a fluid mechanics
virtual laboratory that investigates centrifugal pump cavitation and
performance in a pipe network.
