The emission factor can be determined using carbon balance in fuel and exhaust. An emission test measured the tailpipe exhaust concentration of a diesel truck. The measured exhaust concentrations, vehicle, and fuel properties are given below.

Vehicle and Fuel properties Exhaust concentrations (by volume) Fuel economy

(km/L) 8.5 CO2 12%

Density of Diesel Fuel 0.85 kg/L H2O (water vapor) 11%

Carbon content in diesel fuel (by weight) 86.2% O2 9%

CO 0.05%

NOx as NO2 200 ppm

SO2 10 ppm

If this diesel truck runs 20,000 km (typical mileage) in 2020, how much NOx and SO2 (kg/year) were emitted from this truck in 2020?

1. Projects A and B have the following expected net cash flows: Project A Project B Cash Flow Cash Flow Year 0 1 2 345 3 -$500,000 250,000 250,000 250,000 200,000 150,000 -$500,000 350,000 350,000 300,000 200,000 Both the projects are of the same company, Bit Corporation. The most recently paid dividend was $2 and it is growing at 5% for the infinite period of time. Moreover, the stock is selling for $45. Assume you are a finance manager of the company. a. Calculate the pay back period for both projects. b. Calculate the NPV of both projects. c. Which project should the company choose and why?
