Inflation balance

Solution It is necessary to derive an expression for the inflation time. Referring to Fig. 5.22 where R is the radius of the inflated tube at any time, /, and hi is the wall thickness at this time, then a force balance on the shaded element gives (for unit length). 

Due to its balance of strength, oil resistance, inflammability, increased resistance to ozone, ageing and weathering, polychloroprene finds widespread industrial use. Typical uses are V-belts, conveyor belts, wire and cable jacketing, footwear, wet suit applications, coated fabrics, inflatables, hoses, extrusions and many other goods. Adhesives are also a strong market area. 

If you want to be sure something is left when you die, here s a plan that will work for you. Harvard University s endowment fund developed a spending guideline in 1973 to ensure a person wouldn t prematurely run out of money. The rule assumes a balanced portfolio allocated half to stocks and half to bonds and cash equivalents. It limits the first-year withdrawal to four percent of the portfolio s total value. Then, in each following year, increase this amount by the previous year s rate of inflation. Continue in this manner from year to year. For example, if you have a 500,000 portfolio, you could withdraw 20,000 in the first year. If the rate of inflation were 3.5 percent that year, you could withdraw 20,700 the second year. 

Today s computer technology makes it easy to combine this approach with one designed to deplete capital. With assumptions on inflation, rate of return, and longevity, a withdrawal schedule can be set up. Such a schedule will increase each year by your assumed rate of inflation and carry you through the specified number of years. With such a spending plan, it is imperative that you monitor your assumptions and make adjustments as required. One simple way to do this is to calculate a capital balance for each year into the future. Then, compare your actual balance to this figure. 

After writing mass balances, energy balances, and equilibrium relations, we need system property data to complete the formulation of the problem. Here, we divide the system property data into thermodynamic, transport, transfer, reaction properties, and economic data. Examples of thermodynamic properties are heat capacity, vapor pressure, and latent heat of vaporization. Transport properties include viscosity, thermal conductivity, and difiusivity. Corresponding to transport properties are the transfer coefficients, which are friction factor and heat and mass transfer coefficients. Chemical reaction properties are the reaction rate constant and activation energy. Finally, economic data are equipment costs, utility costs, inflation index, and other data, which were discussed in Chapter 2.

Latin America is usually defined to include Mexico, The Caribbean, Central and South America. This market region includes about 370 million inhabitants. The individual countries represent a wide range of political, social, and economical scenarios. High inflation rates and large trade balance deficits are prevalent in many of the countries. Limited infrastructure (e.g. highways, public utilities, etc.) has seriously hampered their economic growth. However, strong raw material positions (e.g. petroleum, metal ores, etc.) have enhanced export income and helped improve the national GNP and levels of industrialization. For example, three major oil fields have been discovered in Mexico within the past few years, and Venezuela s oil-based economy is well known. 

When ammonium nitrite (NH4NO2) is heated, it decomposes to give nitrogen gas. This property is used to inflate some tennis balls, (a) Write a balanced equation for the reaction, (b) Calculate the quantity (in grams) of NH4NO2 needed to inflate a tennis ball to a volume of 86.2 mL at 1.20 atm and 22°C. 

The effect of inflation in the trade sales area has been felt in the period 1979-82. Note in Table III the sharp increase in the calculated unit value of architectural finishes—compared with the static real unit value predicted for 1987 (as compared to 1982). The decrease in housing starts in 1979-82, resulting in lower house paint shipments, has been partially balanced by increased home maintenance. The trade sales market is relatively mature long range, few major formulation changes are expected with little increase in the real value of finished goods.

An employee who invests her lump-sum distribution when she retires receives the rewards and bears the risks of investment. Making appropriate investments allows her to increase her capital faster than inflation shrinks it. As we saw, other deflned-benefit pensions make none but ad hoc adjustments for inflation, and retired employees do not choose the investments that underlie their pensions. With these annuity-based, guaranteed plans in which employers determine investments, retired persons cannot outlive their benefits. However, exhausting or losing one s capital is possible in cash-balance plans, after the lump-sum payment is received at retirement.
