The heat transferred by the condenser is nearest:
A) 25.5 MJ/s
B) 27.5 MJ/s
C) 30.5 MJ/s
D) 32.5 MJ/s
A) 25.5 MJ/s
Heat transferred by the condenser goes for a useful purpose or it is discarded to the atmosphere with a cooling tower or to a river or large lake. For this problem, it is
Q C = m ( h1 ? h4 )
= 12 × [ 251? ( 251+ 0.9× 2358)] = ?25 500 kJ/s or ?25.5 MJ/s

Graph these signals versus time. Graph the magnitudes and phases of the CTFT’s of these signals in either the f or w form, whichever is more convenient. In some cases the time graph may be conveniently done first. In other cases it may be more convenient to do the time graph after the CTFT has been found, by finding the inverse CTFT.
