Below is a photo of a water-jet amusement ride.
a) Concisely explain how fluid mechanics keeps this person elevated.
b) Derive an equation to estimate the total volumetric flow rate Q required to keep the person
elevated. (You must identify which parameters matter in this situation.)
c) Comment on the sensitivity of this flow rate to the weight of the person lifted (e.g. if the weight
is doubled, how must the flow rate change?)
d) From your equation in (b), make a quantitative estimate for the total volumetric flow rate in this
image based on reasonable estimates of conditions, dimensions, etc. (Rough estimates are
acceptable. Thus, you do not need to look up any information, but just use the image. Remember
that if you do choose to consult resources outside of the course materials, this could be acceptable,
but then you must document and cite them here.)
