A water gun can be a fun toy in a hot summer day. A water gun expels water stored in the acceleration chamber through a nozzle when a trigger is pulled. The water in the acceleration chamber is expelled using a piston attached to a spring. Consider a water gun having the following design parameters: Nozzle diameter: 5 mm Acceleration chamber diameter: 5 cm Acceleration chamber length: 15 cm Spring constant: 100 N/m
a. Determine the maximum velocity of the water stream you can generate using the water gun.
b. Determine the time needed to expel all the water from a fully filled acceleration chamber.
c. If the same spring is retained, and you can change one of the design parameters. Discuss and justify which design parameter and in what manner would you change the design parameter in order to increase the reach of the water stream generated.
d. If the same spring is retained, and you can change one of the design parameters. Discuss and justify which design parameter and in what manner would you change the design parameter in order to increase the force of the water stream generated.
