Question

2) Deriving Expressions for Entropy Generation In this problem you will use your combined 1 and 2"d Law knowledge to derive two expressions, given in lecture without proof, for the rate of entropy generation in different systems. a) A resistance heater is operating steadily in a room filled with ideal gas. The room can be approximated as air-tight, but it exchanges heat with the surroundings to maintain a inside the room, where I and Vare constant temperature Troom. Show hurinside the room, where / and V are the current and voltage applied to the resistor. b) Liquid water is flowing steadily in a pipe with a pressure drop. ΔΡ, while enough heat transfer occurs through the walls of the pipe to keep the water isothermal during this process.Show that Spe rinside the pipe, where v is the specific volume of the hat Saen -inside the pipe, where v is the specific volume of the water water and ΔΡ P-Po.
