In optimum vacuum the heat loss in exhaust of steam is
approx 450 kj/kcal. the temp. at the exhaust is 45. if the
vacuum drops in condenser the exhaust temp. will increase
as the exhaust temp. Increases the heat loss through the
condenser. it will reduce the overall efficiency of the
turbine. (pl. refer steam table for the temp. according to
the condenser pressure.)

i just wanted to ask that what should one do to clear all the concepts a mechanical engineer needs to have cleared,this not only includes the concepts of each and every semester of his engineering course, but also the basic laws and fundamentals of physics(that required for Mechanical engineering).I am a third year mechanical engineering student and i am very keen to know about the above question. somebody please help me.
