Asteam power plant operates on the reheat rankine cycle. steam enters the high-pressure turbine at 12.5 mpa and 550°c at a rate of 7.7 kg/s and leaves at 2 mpa. steam is then reheated at constant pressure to 450°c before it expands in the low-pressure turbine. the isentropic efficiencies of the turbine and the pump are 85 percent and 90 percent, respectively. steam leaves the condenser as a saturated liquid. if the moisture content of the steam at the exit of the turbine is not to exceed 5 percent, determine

(a) the condenser pressure,
(b) the net power output,
(c) the thermal efficiency.

answer:

constructing a building's framework requires a solid foundation

explanation:

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only

d) i and ii only
