QUESTION
Soalan
You serve as an engineering consultant for a new phase in the heat transfer process of a power
plant project while collaborating with your company. Your responsibility involves assessing the
design proposal for the development of a steam condenser designed to condense steam, formed
in conjunction with air and other noncondensable gases, and subsequently removing them
continuously through pumps. As an engineer, you have adhered to design considerations and
assumptions. Thetotal absolute pressureat the entry of the condenser is assumed to remain
constant and is equal to the sum of the partial pressure of air and the saturation pressure of
steam entering the condenser. This assumption persists throughout the condenser due to the
small velocity of the steam flow. The condenser's specifications include handling steam with a
dryness fraction of and a temperature range of to at a rate of Given
an estimated air leakage of and the gas constant, for air is considered as
