. The purchased cost of 200000 inch3 stainless hemispherical tank in 1996 was RO 10700. If the tank is covered fully with 2 inch thickness magnesia block, estimate the present total cost for installed and insulated tank. The cost for covering 2 inch magnesia was 5.1 RO per ft2 and installation labor cost 4.3 RO per ft2 .

**I am submitting 2 solutions for the
problem.**

**One with no change in cost index value and the other
with change in the cost index value with time.**

**In the second one we can directly find the cost by just
putting the respective cost index value.**

**If you have any doubts.. You can ask me in comment
box.**

**Thanks**

Reacting chemicals are stored in a spherical stainless steel
container of outer radius ro = 6 cm and of inner radius is 5 cm.
The chemicals generate a uniform heat at a constant rate of ???? ̇
= 8 × 107 W m3 ⁄ . The outer surface of the container is maintained
at a uniform temperature of 100 °C. Consider a steady
one-dimensional heat transfer and
a. Write an appropriate form of heat conduction equation for the
sphere.

A 1000 gallon (133.7ft^3) propane tank is to be constructed as
cylinder with two hemispherical ends. The design is constrained
such that the total length from one end to the other is twice the
diameter. Determine the following:
- The diameter of the tank in feet
- The overall length of the tank
- The volume of steel required if the tank wall is 1/4 -
thick. Note that the volume of the walls can be calculated by
multiplying the...

A water tank consists of a cylindrical part of radius r and height h and a hemispherical top. The tank is to be constructed to hold 600 m3 when filled. The surface area of the cylindrical part is 2πrh, and its volume is πr2h. The surface area of the hemispherical top is given by 2πr2, and its volume is given by 2πr3/3. The cost to construct the cylindrical part of the tank is $400 per square meter of surface area;...

Sulfur dioxide, and only sulfur dioxide, is contained in a
stainless steel tank. The temperature and pressure inside the tank
can be adjusted to any desired values. What is the maximal number
of solid forms of sulfur dioxide that can exist inside the tank? If
liquid sulfur dioxide is present, how many solid forms can exist?
If instead of a liquid the vapor form of sulfur dioxide is present,
how many solid forms can exist? Finally, suppose both a vapor...

To clean the impeller blades of a stainless steel tank, plant
technicians pour 210.0 L of a 240.0 g HNO3/L solution in a 820.0-L
tank to soak. When the tank needed to be emptied, the tank was
first filled with water entering at a rate of 1.90 L/s. (Figure 1).
At t = tF, the tank is completely full of solution. At this point
water continued to enter the tank at the same rate, but solution
was also drained from...

The Clap Chemical Company needs a large insulated stainless
steel tank to expand its plant. A recently closed brewery has
offered to sell their tank for $15,000 delivered. The price is so
low that Clap believes it can sell the tank at any future time and
recover its $15,000 investment.
Installing the tank
will cost $9000 and removing it will cost $5000. The outside of the
tank is covered with heavy insulation that requires considerable
maintenance. This will cost $3500...

a) A Company purchased equipment for RO 50,000 with an

2. Which of the
following statements is (are) correct?(x) Suppose that the CPI was 200 in 2006 and was 160 in 1996. Then
according to the CPI, $100 in 2006 purchased the same amount of
goods and services as $80 in 1996.(y) A worker received $5 for a daily wage in 1930. If the CPI was
17.4 in 1930 and is 215.6 today then the value of that 1930 wage in
today’s dollars is more than $68.25 but less than...

You own a house that cost $200000 to build. You buy a $15000

you pay for all repairs yourself. If the house suffers $45000, in
damage, you pay$25000 and the insurance company pays the remaining
