A garden hose attached with a nozzle is used to fill a 20-gal bucket. The inner diameter of the hose is 1 in, and it reduces to 0.4 in at the nozzle exit. The average velocity in the hose is 5.6 ft/s. Determine:

a. The volume and mass flow rates of water through the hose.
b. How long it will take to fill the bucket with water.
c. The average velocity of water at the nozzle exit.

If you were designing a bumper for a car, would you prefer it to exhibit elastic or plastic deformation? why? consider the functions of a bumper in both a minor "fender-bender" and a major collision.

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise

You are making beer. the first step is filling the glass carboy with the liquid wort. the internal diameter of the carboy is 15 in., and you wish to fill it up to a depth of 2 ft. if your wort is drawn from the kettle using a siphon process that flows at 3 gpm, how long will it take to fill?
