Size an afterburner and specify the flow rate of methane needed to control 500 m3 min-1 of air from a rendering plant. The exhaust gasses are available at 200°C, and must be raised to 700°C and held for 0.8 sec to reduce emissions of odorous compounds. The burner requires ambient air at a mass ratio of 14:1.

For each of the following process: a) sketch the p-v diagram, b)sketch t-s diagram, c) sketch t-v diagram, d) sketch the boundary work on one of the diagrams (a, b or c) and e) sketch the reversible heat transfer on one of the diagrams (a, b or c): 1- isobaric process from compressed liquid to superheated vapor 2- isothermal process from compressed liquid to superheated vapor 3- isentropic process from compressed liquid to superheated vapor
