Question a power plant operates at a 330 efficiency during, Ask an Expert

Academics

Question: A power plant operates at a 33.0% efficiency during the summer when the seawater used for cooling is at 20.0°C. The plant uses 330°C steam to drive turbines.

Part A: If the plant's efficiency changes in the same proportion as the ideal efficiency, what would be the plant's efficiency in the winter, when the seawater is at 10.3°C?

I need help to find what would be the plant's efficiency in the winter.
