Question 2 Answer the following question and give justifications: a) Hassan is assigned to purchase a flow meter that can be used to measure an expected discharge of a contaminated liquid stream from a chemical complex at a rate of 1x10 m /day. He bought a device that has a range of 20 - 40 ft/s, would this device be reasonable? Why? b) Two students were working in a lab to determine experimentally the viscosity of the same substance. Student A found the viscosity to be 10.0 Pa s, and student B was able to find the viscosity to be 6.0 lbm ft'st check if both have a close answer or not. c) You went to a car dealer to rent a car and you found two cars for rental car 1 consumes 2 gallons for every 60-mile distance travelled, and car 2 consumes 1 liter for every 10 km distance travelled. Which car would you choose to rent? Why? d) The following equation relates the moving mass (m) to the resting mass (mo) of a particle in terms of its speed (w) and the speed of light (c) as: mo V1 - Where would you place the constant c to make the equation dimensionally consistent? Why? m
