Question
A Lassonde Startup Company aims to expand its pump business into rural areas, where accessing
clean water from underground wells can be challenging. Often, families struggle to extract water
manually from the wells, making it difficult for them to meet their water needs. To address this
issue, the marketing team of this Startup Company plans to promote their new centrifugal pumps,
which can be installed in wells, making clean water more easily accessible to the local community.
Additionally, this initiative will help raise awareness about their company within the region.
In the new model of the pump, water leaves the impeller with a velocity of 25 m/s and an
acceleration of 30 m/s², measured relative to the impeller along the blade line AB. The impeller
rotates at a constant angular velocity ofw = 15 rad/s.
