You got a job at an airport refueling planes. Midway Airport wants all employees to refuel planes at the rate of 200 liter/min. The refueling hose has a diameter of 8 cm with one end connected to a pump 1 m above the ground. At the other end of the hose is a 5.1 cm diameter nozzle that connects to the plane 5.2 m above the ground. (Take the specific gravity of gasoline to be 0.700)
(a) Find the speed of the fuel at the nozzle,
(b) the speed of the fuel in the line near the pump,
(c) the pressure difference between the pump and the nozzle

PRACTICE IT Use the worked example above to help you solve this problem. A water hose 2.15 cm in diameter is used by a gardener to fill a 31.0-liter bucket. (One liter = 1,000 cm3.) The gardener notices that it takes 1.00 min to fill the bucket. A nozzle with an opening of cross-sectional area 0.500 cm2 is then attached to the hose. The nozzle is held so that water is projected horizontally from a point 1.00 m above the...

AL Figure P9.28 it 29. A sample of an unknown material appears to weigh 300. N in air and 200. N when immersed in alcohol of specific grav- ity 0.700. What are (a) the volume and (b) the density of the material 30, An object weighing N in air is immersed in water after being tied to a string connected to a balance. The scale now reads 265 N. Immersed in oil, the o object appears to weigh 275...
