1. How does the actual flow rate through the gate compare to the theoretical flow rate through the gate based on Bernoulli’s equation?2. Plot the head loss at the sluice gate verse slope. How does the head loss at the sluice gate change with the slope?3. Plot the actual and theoretical head loss at the hydraulic jump verse slope. How does the head loss at the hydraulic jump change with the slope?4. Compare the actual and theoretical head loss at the hydraulic jump.

People with normal vision cannot focus their eyes underwater if they aren't wearing a face mask or goggles and there is water in contact with their eyes. in a simplified model of the human eye, the aqueous and vitreous humors and the lens all have a refractive index of 1.40, and all the refraction occurs at the cornea, whose vertex is 2.60 cm from the retina.with the simplified model of the eye, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (be careful-the focal length of a lens underwater is not the same as in air! assume that the corrective lens has a refractive index of 1.62 and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. assume that the eyeglasses are 2.05cm in front of the eye.)
