1. A power plant operates based on the flow diagram. Assume that the pipes, boiler, and superheater are well insulated and that friction can be neglected. Note: the quality of steam is the weight fraction that is vapor in a mixture of vapor and liquid. Determine in BTU Ibm steam : A. The heat transferred to/from the boiler. (5 points) B. The heat transferred to/from the super heater. (5 points) C. The heat transferred to/from the condenser. (5 points) D. The shaft work transferred to/from the turbine. (5 points) E. The shaft work transferred to/from the liquid pumps.
