Water is the working fluid in a regenerative Rankine cycle. The pressure and temperature at the turbine inlet are 8MPa and 550 °C, respectively, and the condenser pressure is 7.5KPa. The mass flow rate of steam entering the turbine is 176kg/s. Included in the cycle is one closed feed water heater using extracted steam at 1800KPa and one open feed water heater operating at 275KPa. Saturated liquid condensate is throttled from the closed feed water heater at 1800KPa to the open feed water heater. The feed water leaves the closed heater at 8MPa, 200 °C, and saturated liquid leaves the open heater at 275KPa. The cooling water experiences a temperature increase from 15 °C to 27 °C with negligible pressure drop as it passes through the condenser. Draw the T-s diagram (hint: it would help to begin with a schematic of the cycle) and
Determine:a. The net power developed in KWb. The thermal efficiency of the cyclec. The mass flow rate of cooling water in kg/s
Water is the working fluid in an ideal Rankine cycle. Saturated vapor enters the turbine at 18 MPa. The condenser pressure is 6 kPa. How do I determine the quality of the fluid at the turbine exit
Plot the spectral blackbody emissive power of the sun versus wavelength in the range of 0.01 micro m to 1000 micro m?
You are to supply a design for an engine room crane which will provide maintenance support for the main engine. Your design should include the rails the crane will sit on.
A steady flow air compressor compresses 50 lb/min from 14 psia and 80 degrees F to a discharge state at 45 psia and 300 degrees F. Heat departs from the air only via circulating water that enters the jacket at 75 degrees F and leaves at 95 degrees..
