It is better if both can be solved.

Answer 1

Define the geothermal power plant type? The mal power plant is geother three mainly types 09 dery steam 1. > Total Flow steam on 2.) flash steam 3.) binary binary cycle. Define turbine isentropic efficiency ? The isentropic efficiency of turbine is defined the ratio of actual work out put turbine to the work output of the turbine if the turbine inlet and exit pressuhe. is entropic 95 same undengoes v between the en process the processes on Its diagram! o Total flow from resenvoies condition (1241 - 975) 266M KIN 100% Total flow from optimised sepanation condition M (1241 - 1031) = 210 kW ,79% ③ Optimised separated steam flow through condensing turbine 0 263 M (2764 - 2146) 163M KW, 61%

Caclulation of power The calculations will carried out for a binary power plant with enhanced geothermal hesenvoin (EGS) as the geothermal be resource. The power generated by the geothermal power plant from 14.13 M IN to 21.33 MN.
