Balancing method

Fuel economy is measured usiag a carbon balance method calculation. The carbon content of the exhaust is calculated by adding up the carbon monoxide (qv), carbon dioxide (qv), and unbumed hydrocarbons (qv) concentrations. Then usiag the percent carbon ia the fuel, a volumetric fuel economy is calculated. If the heating value of the fuel is known, an energy specific fuel economy ia units such as km/MJ can be calculated as well. 

Other commonly used methods of computing depreciation are the declining-balance method (also known as the fixed-percentage... 

The declining-balance method of depreciation allows equipment or plant to be depreciated by a greater amount during the earlier years than during the later years. This method does not allow equipment or plant to be depreciated to a zero value at the end of the service life. 

Balanced design method A method of duct sizing to ensure the correct airflow rate in all branches, also known as the static pressure balancing method. 

The example below illustrates the application of the alumina balance method. 

Material balance method (pressure decline method)... 

D. Balancing method (Section 17.5). This method forms the basis of all colorimeters of the plunger type, e.g. in the Duboscq colorimeter. The comparison is made in two tubes, and the height of the liquid in one tube is adjusted so that when both tubes are observed vertically the colour intensities in the tubes are equal. The concentration in one of the tubes being known, that in the other may be calculated from the respective lengths of the two columns of liquid and the relation [equation (11)] ...

Eor saturated surfaces, the Bowen ratio can then be used to calculate evapotranspiration as a residual of the surface energy balance (Penman, 1948). Since direct measurement of ET is difficult and expensive, the energy balance method is fairly common. 

When solid particles are subject to noncatalytic reactions, the effects of the reaction on individual particles are derived and then the results are averaged to determine overall properties. The general techniques for this averaging are called population balance methods. They are important in mass transfer operations such as crystallization, drop coagulation, and drop breakup. Chapter 15 uses these methods to analyze the distribution of residence times in flow systems. The following example shows how the methods can be applied to a collection of solid particles undergoing a consumptive surface reaction. 

Still using the framework of Section 2, a difference scheme for equation (26) can be obtained by the balance method ... 

So far we have studied some versions of the IIM on the basis of the balance equation (the balance method). We now consider the second method for the design of homogeneous difference schemes by means of the IIM, in the framework of which equation (1) has to be integrated twice first, we integrate equation (1) from to x ... 

The measurement of carotenoid absorption is fraught with difficulties and riddled with assumptions, and it is therefore a complex matter. Methods may rely on plasma concentration changes provoked by acute or chronic doses, oral-faecal mass balance method variants and compartmental modelling. 

In the traditional balance method, the apparent absorption of a carotenoid or any other pigment is determined by the difference between its intake (inpnt) and its excretion (ontpnt). This techniqne requires carefnl measurements of all inpnt and ontpnt of the compound of interest. The approach has the advantage of being non-invasive and thns able to be used directly on hnman subjects. 

A plant costs 6,000,000 and is expected to last 6 years. Its salvage value is negligible. Calculate the rate of depreciation using the double declining balance method. 

But earnings are not the only consideration. In 1968 the Union Carbide Corporation, along with many other companies, had a very bad year financially. In order to make its financial picture look better it switched from the double declining balance method of depreciation to the straight-line method. This reduced expenses (deprecitation being considered an expense) and hence increased profits. This is a semipermanent move, however, since a return to the double declining balance method would require approval of the Internal Revenue Service. 

Problem 2. Why is the salvage value not considered when depreciation for the double declining balance method is calculated ... 

It has a salvage value of 2000,000 and a net salvage value of 1,200,000. Assume the plant will last 7 years. Use (a) straight-line depreciation (b) double declining balance method (c) sum of the years-digits method...
