ECOR 1010 – INTRODUCTION TO ENGINEERING SAMI NOFAL ASSIGNMENT #1 The Most Efficient Vehicle TO Marking TA: Name: Chirag Sharma Email: firstname.lastname@example.org Lab Section: A1 Room: ME2556 – Carleton University FROM: Email: email@example.com Student Number: 100968375 Number of Figures and Tables (Including handwritten ones): 3 tables Last Date and Time of Revision: 19 September 2014 [Type here] Nofal, Sami [Type here] INTRODUCTION Two Manufacturers claimed that their product uses less fuel. Therefore, the aim of this report is to investigate which product has more fuel efficiency than the other. The aircraft manufacturer states “People traveling by air consume approximately half the fuel that a person would traveling by automobile”. The automobile manufacturer claims that “People should travel by car because they will consume less fuel”. The following results will be obtained: Fuel consumption, Fuel cost, carbon dioxide emission, time travel and finally the number of trees to offset carbon dioxide. These results will prove which manufacturer was right. MATERIALS AND METHODS The lab includes three tables, with spaces to calculate the results, and one figure. A “Studio fx-991ES” calculator was used to calculate complex calculations in this lab. All calculations were handwritten and scanned to the Microsoft word document. Significant figures in this lab were put in table 3 by reference to chapter 11 section 6 from the “Introduction to Engineering book”. Despite the fact that some of the sig figs are not correct, basic knowledge was used to make the data accurate. The conversion unit: 0.453592 from pound (lb) to kilogram (kg) was taken from the internet. The rounded number is put in a box in the calculation sheet. RESULTS The results of this lab show that when an automobile is fully occupied, it is more efficient than a fully occupied airplane. Since airplanes consume (3.11 L/100Km) almost double what both minivan (1.69L/100km) and sedan cars (1.69L/100km) consume. This means that the airplane manufacturer was mistaken when he said that airplanes are more efficient. Although planes help you arrive in a shorter time but they produce about 47% more carbon dioxide than a sedan car and 63% more than a minivan, per person. According to the results automobiles consume less fuel and emit less carbon dioxide per person but consume much more time than airplanes do. These results show that the airplanes manufacturer was mistaken. DISCUSSION The Airplane Manufacturer claim can be proven right only if the automobile was 25% occupied since the fuel consumption will quadruple per person. This means a person driving an automobile that is 25 % occupied will consume about 6.75 L/100km for a sedan and 8.75L/100km for a minivan. In this case the airplane manufacturer’s claim was true. If all three vehicles were fully occupied the most fuel efficient one is a minivan consuming 1.25L/100km per person. An automobile manufacturer can claim that people can travel by an automobile with half the fuel consumed by air CONCLUSIONS To sum up, it is shown by this report that automobiles are more fuel efficient and produce less greenhouse gases to the environment when fully occupied. If automobiles are 25% occupied it is preferred to travel by air since it consumes less fuel and emits less carbon dioxide to the environment. This lab also concludes that traveling by air can also save much more time than traveling by a car or minivan. 2 [Type here] Nofal, Sami [Type here] APPENDICES- FIGURES AND TABLES Table 1: “BlueSky” model E-1010 airplane specifications.

Нормально, - высокомерно бросила. - А тебе здесь делать нечего. Беккер повернулся, печально посмотрев в последний раз на ее руку.
