Question

a
tank holds 90 gal of water which drains from a leak at the bottom,
causing the tank to empty in 32 min. The tank drains faster when it
is newrky full because the pressure on the leak is greater.
Toricelli’s Law gives the volume of water remaning in the tank
after t minutes as

v(t)=90(1-t/32)^2

0<t<32

(a) find v(0) and v(32)

(b) make a table of values of v(t) for t=0,8,16,24,32 (round
tiur answer to three decimal places)

(c) find the net change in the volume V as t chmages from 0
min to 32 min

A tank holds 100 gallons of water, which drains from a leak at
the bottom, causing the tank to empty in 40 minutes. According to
Toricelli's Law, the volume V of water remaining in the tank after
t min is given by the function V = f(t) = 100 1 − t 40 2 . (a) Find
f −1. f −1(V) = $$ Correct: Your answer is correct. What does f −1
represent? f −1 represents the rate at which...

A raised water tank has a leak at the bottom which causes the
water surface to drop from elevation 4.88m to elevation 4.57 m in a
period of 12 hours. (a) What will be the elevation of the water
surface in the tank after 5 full days (starting from elevation
4.88m) if no water other than the leaking water is either added or
drained from the tank? The bottom of the tank is at elevation zero.
(b) How long will...

A tank initially holds 100 gal of brine solution. At t = 0,
fresh water is poured into the tank at the rate of 5 gal/min, while
the well-stirred mixture leaves the tank at the same rate. After 20
min, the tank contains 20/e lb of salt. Find the initial
concentration of the brine solution inside the tank. Ans.: 0.20
lb/gal

A tank contains 100 gallons of pure water. A salt solution with
concentration 2.5 lb/gal enters the tank at a rate of 4 gal/min.
Solution drains from the tank at a rate of 4 gal/min. Find the
eventual concentration of the salt solution using a qualitative
analysis rather than by actually solving the DE.

(1 point) A tank contains 1520 L of pure water. A solution that
contains 0.04 kg of sugar per liter enters the tank at the rate 8
L/min. The solution is mixed and drains from the tank at the same
rate.
(a) How much sugar is in the tank at the beginning? y(0)=
(b)Find the amount of sugar (in kg) after t minutes. S(t)=
(c)Find the amount of the sugar after 90 minutes. S(90)=

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 tank contains 90 kg of salt and 2000 L of water: Pure water
enters a tank at the rate 8 L/min. The solution is mixed and drains
from the tank at the rate 8 L/min. What is the amount of salt in
the tank initially? Find the amount f salt in the tank after 4.5
hours. Find the concentration of salt in the solution in the tank
as the time approaches infinity. (Assume your tank is large enough
to...

A 50-gallon tank initially contains 10 gallons of fresh water.
At t = 0, a brine solution containing 2 pounds of salt per gallon
is poured into the tank at a rate of 5 gal/min. The well-stirred
mixture drains from the tank at a rate of 3 gal/min. Find the
amount of salt in the tank at the moment of overflow. Please use
differential equations to solve this problem and please put the
answer in decimal form. I did this...

A Tank contains 100g of salt and 500L of water. Water that
contains (5/2)g of salt per liter enters the tank at a rate of 2
(L/min). The solution is mixed and drains from the tank at a rate
of 3 (L/min). Let y be the number of g of salt in the tank after t
minutes. a). What is the differential equation for this scenario?
and b). what is the particular solution given y(0) = 100

A tank contains 2100 L of pure water. Solution that contains
0.05 kg of sugar per liter enters the tank at the rate 44 L/min,
and is thoroughly mixed into it. The new solution drains out of the
tank at the same rate.
(a) How much sugar is in the tank at the begining?
y(0)=
(b) Find the amount of sugar after t minutes.
y(t)=
(c) As t becomes large, what value is y(t) approaching ? In
other words, calculate...
