Problem 2: Part B Water (4.18 kJ/kg-K) and air (1.005 kJ/kg-K) flow through a cross-flow heat exchanger with both fluids unmixed. The water flows at 2.0 kg/s and decreases from 66 °C to 45 °C, and the air flows at 4.2 kg/s and enters the heat exchanger at 20 °C. Using the ε-NTU method, determine the exit temperature of the air (°C)

Cоmplete the fоllоwing stаtements by аdding the missing words or selecting the correct option between the 2 (or 3) аlternatives presented as (X/X or X/X/X):A disadvantage of the __________ method is that it ignores the time value of money. A company should accept a project if the NPV is positive/negative and reject a project if the NPV is positive/negative.The net present value of a project equals the present value/future value of the cash inflows minus the present value/future value of the cash outflows.The IRR of a project is the discount rate that makes the NPV greater than zero/ less than zero/equal to zero.The following is a method of adjustment used for comparing projects of different lives: IRR/Modified IRR/equal annuity.When a company can only fund some of its good projects, it should rank the projects by _________.When we say a company is considering two mutually exclusive projects, it means that the company is considering taking on one/both/none of the projects.
