Heading 2 Example. D h : hydraulic diameter — for pipes is equal to the internal diameter [m]. Re : Reynolds number [-]. L : pipe length [m]. Solutions Here we will discuss five different approaches to the above equation.

The degree of accuracy differs for each approach, as well as the level of difficulty. So in absolute terms, the project or investment with a higher NPV value should be considered. IRR offers a percentage rate of return which may not be accurate as it takes two random interest rate costs into consideration.

The NPV offers absolute gain or loss in terms of present value; however, the NPV calculations also require a suitable cost of return for assessment. Companies often compare projects and investment options to maximize profits. IRR is one such discounting method that offers insights for future project appraisals.

The IRR analysis is a useful investment appraisal method. It offers advanced information as compared to the simple payback period. The IRR focuses on cash flows in present value terms that emphasize company liquidity than profitability.

The possible IRR evaluation and NPV appraisal can be used in conjunction to arrive at a better investment appraisal analysis. Expression Equation Inequality Contact us. Solve Graph System.
