Question

- A student fills a tank of radius .15m with water to a height of .5m and pokes a small, 1.0 cm diameter hole at a distance 0.03m from the bottom of the tank. The water flows out of the small hole into an empty, 0.2 m diameter container placed below the tank. The student uses a garden hose to keep the water level in the tank at the original height.

- What is the velocity of the water as it leaves the hole near the bottom of the tank? (4 pts)

- What is the volume flow rate of water from the garden hose into the tank? (hint: what is the flow rate out of the tank?) (4 pts)

- After 60 seconds of operation, what is the water pressure at the bottom of the container used to catch the water leaving the tank? (6 pts)

Answer #1

Water flowing through a garden hose of diameter 2.78 cm fills a
22.0 L bucket in 1.50 min.
(a) What is the speed of the water leaving the end of the
hose?
(b) A nozzle is now attached to the end of the hose. If the
nozzle diameter is one-third the diameter of the hose, what is the
speed of the water leaving the nozzle?

Water flowing through a garden hose of diameter 2.73 cm fills a
21.0-L bucket in 1.35 min.
(a) What is the speed of the water leaving the end of the
hose?
(b) A nozzle is now attached to the end of the hose. If the
nozzle diameter is one-third the diameter of the hose, what is the
speed of the water leaving the nozzle?

A jet of water squirts out horizontally from a hole near the
bottom of the tank shown in the figure. If the hole has a diameter
of 5.95 mm, what is the height h of the water level in the tank? x=
.600 m y=1.00 m

A large cylindrical tank containing water to a level of 5.00 m
above the bottom of the tank is elevated such that the bottom of
the tank is 5.00 m off the ground. A hose with a length of 3.00 m
and a radius of 1.50 cm is attached to the bottom of the tank and
allowed to hang vertically down. Water begins to drain out from the
end of the hose. The density of water is 1000 kg/m3.
(a)...

The height of water in a small tank shaped as a right-circular
cone (cf. a filter funnel) is changing at 4.25 cm/min. The flow
rate of water into the tank is 1.25 kg/s, while the flow rate out
is 1.15 kg/s. The height of the tank is 65.0 cm and its diameter is
75.0 cm. What is the water level within the tank?

The
hose has a diameter of 2.5 cm, but the nozzle has a diameter of
only 1.10 cm. The water that comes out of the hose fills a
container of 25 Len 1.50 min. Calculate: a- the volume flow flowing
through the hose b- the velocity of the water leaving the nozzle c-
if the pressure external to the hose is atmospheric, what is the
absolute pressure of the water inside the hose?

Suppose water is leaking from a tank through a circular hole of
area
Ah
at its bottom. When water leaks through a hole, friction and
contraction of the stream near the hole reduce the volume of water
leaving the tank per second to
cAh
2gh
, where
c (0 < c < 1)
is an empirical constant.
A tank in the form of a right-circular cone standing on end,
vertex down, is leaking water through a circular hole in its...

A large storage tank, open at the top and filled with water,
develops a small hole in its side at a point 16.8 m below the water
level. The rate of flow from the leak is found to be 3.00 10-3
m3/min. (a) Determine the speed at which the water leaves the hole.
22.22 Incorrect: Your answer is incorrect. The water speed at the
top of the tank can be assumed to be zero since the flow rate from
the...

A pump is filling a cylindrical water tank 30 feet in diameter
and 30 feet high. The pump flow rate is 500 GPM, after 2 hours of
operation, the pressure exerted from the water on the bottom of the
tank is _____ psi. (Assume that the tank was empty prior to the
pumping process)

A pump is filling a cylindrical water tank 25 feet in diameter
and 25 feet high. The pump flow rate is 300 GPM, after 2 hours of
operation, the pressure exerted from the water on the bottom of the
tank is _____ psi. (Assume that the tank was empty prior to the
pumping process)
