The condensing pressure for a Rankine engine is 0.001325 MPavac. Calculate the following for steam flow rate = 16.3846 kg/sec of steam when the steam at the beginning of expansion is at 119.6 deg SH and 4.0 Mpaa. Draw the TS and equipment diagrams for the ideal and actual case and find for the following for the ideal case:
ercise 6 6.1 A surface condenser is fitted with separate air and condensate outlets. A portion of the cooling surface is screened from the incoming steam and the air is passes over these screened tubes to the air extraction and becomes cooled below the condensate temperature. The condenser receives 20 000kg/hr of dry saturated steam at 36.2°C. At the condensate outlet the temperature is 34.6°C TK and at the air extraction the temperature is 29°C. The volume of air and vapour leaving the condenser is 3.8m3/min. Assume constant pressure throughout the condenser, calculate: 6.1.1 the mass of air removed per 10 000kg of steam (2.63kg); 6.1.2 the mass of steam condensed in the air cooler per minute (0.5kg/min)%3B 6.1.3 the heat rejected to the cooling water (13451kW).
In the condenser of the power plant, Ammonia is isobarically condensed to saturated liquid state with 615.2kPa and x = 0.9, the mass flow rate is 4 t/h. The heat rejected from the condensing ammonia is added to heat water, which is heated from 277K to 281K. What is the mass flow rate of water in t/h. Also sketch the T-s and P-v diagrams.
Steam is supplied to a two-stage turbine at 40 bar and 350°C. It expands in the first turbine until it is just dry saturated, then it is re-heated to 350°C and expanded through the second-stage turbine. The condenser pressure is 0.035 bar. Calculate the work output and the heat supplied per kilogram of steam for the plant, assuming ideal processes and neglecting the feed-pump term. Calculate also the specific steam consumption and the cycle efficiency
Steam is generated at 10 MPa and 450OC and condensation occurs at 170 kPa. (a)For a Rankine engine operating between these limits, compute the thermal efficiency and the heat rate. (b) Considering that a Rankine cycle occurs between the limits, determine QA, QR, WNet, and eC. (c)What mass flow rate is required for a net output of 35 MW?
The evaporator (a heat exchanger) in an A/C unit has R-410A entering at -20 °C and a quality of 30% and leaves at the same temperature and a quality of 100%. The COP of the air conditioner is known to be 1.3 and the mass flow rate is given as 0.013 kg/s. Find the power input to the cycle. (Note that, here, the evaporator is the part of the A/C unit that accepts [i.e., withdraws] heat from the room maintained at a cold temperature)
Oren is hired to design a massive 450 MW power plant for the city of Dubai. Oren decides that the optimal efficiency would be obtained if the pressure of saturdted vapár entering the turbine should be 10 MPa.and the presJure of saturated liquid exiting the condensor to be 0.005 MPa. Dubai is in the United Arab Emirates (UAE), where the water from the Persian Gulf is 4O °C and UAE environmental laws limit the exiting coa ling water to a maximum temperature of 45°C (to prevent damage to local fishing industry). For Oren's power plant, calculate : A.) heat input from the boiler (in MegaWatts) B.) thermal efficiency C.) mass flow rate of caoling water (in k/s)
