An important dimensionless parameter in certain types of fluid flow problems is the froude number defined as v√gℓ, where v is a velocity, g the acceleration of gravity, and ℓ a length. determine the value of the froude number for v

Farmer a has a deep well and needs a lot of water for her animals and crops. her neighbor, farmer b, has a shallower well. he needs less water than farmer a because his farm is smaller. in years of drought, sometimes farmer b can't get any water from his wells. what can farmer b do to decrease the likelihood of his well running dry?
