Q1) Select TRUE or FALSE For the Following Statements: 1. When some steam extracted from the turbine to pre-heat the liquid which is exiting the pump this process is called Regeneration. 2. In closed feed-water heater the extracted steam from the turbine is mixed directly with the incoming subcooled water to produce saturated steam at the extraction steam pressure. 3. An open feed-water heater is treated as a mixing chamber. 4. In closed feed-water heater type, we need an additional pump for each closed feed- water. 5. Cogeneration is the simultaneous generation of electricity and steam. net work 6. The utilization factor for cogeneration plant = total heat input 7. In bottoming cycle cogeneration the steam is used directly for process steam requirements, the turbine in this case is called a back-pressure turbine. 8. For the following fig. the turbine and the pump work ideally 9. 4s
