A long-insulated tube is made of an exothermic material which generates steady and uniform heat at rate of q [W/m³]. The tube has an inner radius r1 and outer radius r2. The temperature of the outer insulated surface is T2. This tube is used to heat a liquid flowing through it. Write the governing differential equation with the boundary conditions to determine the temperature distribution inside the tube and determine the heat flux supplied to the liquid by the tube.

3.- What does a technical study consist of?  (In the evaluation of projects)

At Axiom Space you work with other astronautical engineers to combine your mechanical and creative talents and design the new spaceship and the crew’s accommodation.   What shape will you give the new spaceship? What factors will you consider before deciding on the shape? Explain. Sketch your design.

Jeff was just hired by GSI, Inc. to be their Environmental and Safety Coordinator.  This is Jeff's first position after completing his engineering degree.  He had taken a course in safety engineering as part of his studies and felt confident that he could handle the job. Management at GSI, Inc. has assured him that they are committed to maintaining a safe workplace.  They have never had an individual dedicated to this task full-time.  They will implement his recommendations if he can justify them. As Jeff begins to get familiar with the operations, he spends considerable time on the production floor.  He notices workers clean their tools before break with a liquid from an unmarked 55-gallon drum.  They also use this liquid to clean residue from their skin.  They use paper towels to dry their tools and hands, throw these towels in the trash, and head to the break room for a snack and/or smoke. In talking with the workers, Jeff learns of some of their concerns.  Several people mention…
