Chapter 7, Problem 7.109(choose chapter or problem)
Air enters the insulated duct shown in Fig. P7.109 at a temperature of 60\(^{\circ}\)F and a pressure of 1 atm and exits at a temperature of 140\(^{\circ}\)F 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 the heater. Let \(T_{0}\) = 60\(^{\circ}\)F, \(p_{0}\) = 1 atm.
