The correct answer is B) manually recirculate condensate and add some makeup feed. The reasoning is that the low main condenser hotwell level and the presence of steam coming out of the gland exhaust condenser vent indicate a problem with the condenser system. This could be caused by a loss of condenser vacuum, leading to decreased condensation of the steam. To address this, the best action is to manually recirculate the condensate and add some makeup feed to the system. This will help restore the proper water level and improve the condenser's performance. The other options are incorrect because they do not directly address the root cause of the problem. Increasing steam pressure to the air ejectors (A) or decreasing gland sealing steam pressure (D) may not resolve the underlying issue of the low condenser hotwell level. Speeding up the condensate pump (C) may not be necessary if the issue is with the condenser itself rather than the condensate system.
