11.In the process of condensing the exhaust steam from the main or auxiliary turbines, steam condensate is recovered and is reused as feedwater. In a properly designed and maintained feedwater system the condensate is collected at the saturation temperature corresponding to compensating pressure. Therefore, which is the false statement? (A)The process inside a condenser is a constant pressure process. (B)The process inside a condenser is a constant temperature process. (C)The process inside an ideal condenser is a isentropic process. (D)The increase of saturation temperature increases the pressure inside a condenser.
