ME-201 Study Guide - Final Guide: Control Volume, Entropy Rate, Ideal Gas
Document Summary
A closed, rigid tank contains 5 kg of air initially at 300 k, 1 bar. 6. 71, the tank is in contact with a thermal reservoir at 600 k and heat transfer occurs at the boundary where the temperature is 600k. A stirring rod transfers 600 kj of energy to the air. The final temperature is 600 k. the air can be modeled as an ideal gas with cv = 0. 733 kj/kg k and kinetic and potential energy effects are negligible. Determine the amount of entropy transferred into the air and the amount of entropy produced, each in kj/k. Known: air undergoes a process in a closed rigid tank. The work is specified and the air receives energy input from a thermal reservoir at a given temperature. Find: determine the amount of entropy transferred into the air and the amount of entropy produced. T1 = 300 k, p1 = 1 bar. T2 = 600 k m = 5 kg.
