Question: a rigid tank of 1 m3 initially contains a mixture...

Question details

A rigid tank of 1 m3 initially contains a mixture of saturated R134a vapor and liquid at a temperature of 20°C and a quality of 0.1 (State 1). A leak develops and saturated vapor slowly escapes from the top. The leak is stopped at the moment when all of the liquid has evaporated (State 2). Heat transfer occurs so that the temperature remains constant. The environmental temperature is 30°C.

(a) Find the mass of R134a which has escaped, in kg. (b) Find the total heat transfer for the process, in kJ. (c) Find the exergy destroyed in the entire system, in kJ.

CV R134a 7-20 °C; Xi = 0.1 į
