I know this depends on some factors, and I can only think of these: the inlet steam's temperature and pressure. If there are more factors then please do tell me.
What is the maximum figure in liters for water that is needed per kWh of electricity generated by solar CSP? Figures on the internet go from a mere 4 liters to 70 liters for every kWh generated? What's right and what's wrong?
Note: I am only considering water for steam, NOT for cooling.
