A nozzle with a radius of 0.250 cm is attached to a garden hose with a radius of 0.700 cm. The velocity of the water in the hose is 1.90 m/s and the velocity of the water in the nozzle is 14.9 m/s Required:
a. Calculate the maximum height to which water could be squirted if it emerges from the nozzle.
b. Calculate the maximum height to which water could be squirted if it emerges with the nozzle removed, assuming the same flow rate.

As shown in fig. p3.64, a closed, rigid tank fitted with a fine-wire electric resistor is filled with refrigerant 22, initially at 2108c, a quality of 80%, and a volume of 0.01 m3. a 12-volt battery provides a 5-amp current to the resistor for 5 minutes. if the final temperature of the refrigerant is 408c, determine the heat transfer, in kj, from the refrigerant.

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 1.90
