A stream of liquid water enters a boiler and emerGes from the boiler as steam. This steam is mixed with a second stream of steam and the mixed steam is fed to a turbine. It emerges from the turbine as a VLE mixture with a quality of 0.96. The entire process operates at steady state.
An engineer draws a control volume that contains the boiler, the turbine and the mixing point. Which of the following is an energy balance that is both correct for this system and consistent with the sign conventions established in this book? A. 0= m ?_(1,in) H ?_(1,in)+ m ?_(2,in) H ?_(2,in)- (m ?_(1,in)+m ?_(2,in) ) H ?_out+W ?_s+ Q ? B. W ?_s+ Q ?= m ?_(1,in) H ?_(1,in)+ m ?_(2,in) H ?_(2,in)- m ?_out H ?_out C. ?-W ??_s= m ?_(1,in) H ?_(1,in)+ m ?_(2,in) H ?_(2,in)- m ?_out H ?_out D. m ?_(1,in)+m ?_(2,in) ?=m ??_out E. All of the above.
