Problem 7.109

Air enters the insulated duct shown in Fig. P7.109 at a temperature of 608F and a pressure of 1 atm and exits at a temperature of 1408F and a pressure only slightly less than 1 atm. Electricity is provided to the resistor at a rate of 0.1 kW. Kinetic and potential energy effects can be ignored. For steady-state operation (a) determine the exergetic destruction rate, in kW.(b) devise and evaluate an exergetic efficiency for theheater.Let T0 5 608F, p0 5 1 atm

What is tribology Fundamentals of Tribology: • Surfaces in Contact • Friction • Lubrication • Wear •Two aspects – Science: Basic mechanisms – Technology: Design, manufacture, maintenance What is Tribology • Tribology is defined as the science of interacting surfaces in relative motion. • The word tribology comes from the Greek tribos, meaning rubbing. • In any machine there are lots of component parts that operate by rubbing together. • Some examples are bearings, gears, cams and tappets, tires, brakes, and piston rings. All of these components have two surfaces which come into contact, support a load, and move with respect to each other. • Sometimes it is desirable to have low friction, to save energy, or high friction, as in the case of brakes. Usually we don't wan
