Question

1) A cylindrical tank with a radius of 10 feet and a height of
20 feet is leaking. An observer notices that the height of the tank
is goinf down at a constant rate of 1 foot per second. At what rate
is the water leaking our of the rank (measured in volume) when the
height of the water is 5 feet? The colume of a cylinder of height h
and radius is V=pi*r^{2}*h.

a. -314

b. - 1,245

c. - 1,570

d. - 100

e. None of these

2) What are the units for the previous problem

Answer #1

Raccoon City monitors the height of the water in its cylindrical
water tank with an automatic recording device. The tank has a
radius of 20 feet. Water is constantly pumped into the tank at a
rate of 2400 cubic feet per hour. If the water level was 16.05 feet
at 6:59 am and 15.95 feet at 7:01 am, estimate the rate at which
the residents of Raccoon City were using water at 7:00 am. Round to
the nearest cubic foot...

A cylindrical can is to have volume 1500 cubic centimeters.
Determine the radius and the height which will minimize the amount
of material to be used.
Note that the surface area of a closed cylinder is
S=2πrh+2πr2 and the volume of a cylindrical can is
V=πr2h
radius =. cm
height = cm

a
cylindrical tank or radius 2 meters and height 7 meters is filled
with water to a depth of 4 meters. how much work does it take to
pump all the water over the top edge of the tank?

A cylindrical oil drum is to be designed so that its height plus
the diameter of its base is five feet. What is the maximum possible
volume for such a drum? [V = pi r^2 h]

A paper cup in the shape of a cone with height 5 cm and radius 3
cm with the point of the cone at the bottom. A small leak develops
in the cup causing water to leak out at a rate of 0.1
cm3/s. Find the rate at which the height of the water in
the cup changes when the depth of the water is 2 cm. Recall that
the volume of a cone is v=1/3(pi)(r2)h

A tank shaped like a cone pointing downward has height 9 feet
and base radius 3 feet, and is full of water. The weight density of
water is 62.4 lb/ft^3. Find the work required to pump all of the
water out over the top of the tank.

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 cylindrical tank of radius R is filled with a liquid of
density to a height H above its bottom. It has a small hole of
radius r in the mantle at distance h above its bottom. Air pressure
equals p0. You are to use Bernoulli’s equation to compute the flow
velocity of the fluid as it exits the hole. a) Prepare a diagram.
Indicate the location of the two points that you choose when
applying Bernoulli’s equation. What...

10. A circular cylinder with a radius R of 1 cm and a
height H of 2 cm carries a charge density of ρV = H r2 sin φ µC/cm3
(r is a point on the z-axis, φ is an azimuthal angle). The cylinder
is then placed on the xy plane with its axis the same as the
z-axis. Find the electric field intensity E and the electric
potential V on point A on z-axis 2 cm from the top...

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...
