an ideal Rankine cycle (fluid flow rate is 8 kg/s) operating between upper and lower pressures of 5 and 10,000 kPa. Draw a schematic of the components of this cycle. Draw the cycle on a P-v phase diagram and a T-s diagram. Find the power output of the turbine, the power input needed for the pump, and the overall cycle thermal efficiency.

In a standard Rankine cycle steam enters the turbine at pressure p3=10mpa and temperature T3=350cThe exit pressure of the steam from the turbine is p4=10kpa A. What is the quality of the steam leaving the turbineB. What is the thermal efficiency of the cycle? C. Reduce the turbine inlet pressure to 3.5 MPa.In this situation, the steam quality at the exit of the turbine will be x = 0.801, and the thermal efficiency will be 34.1%State an advantage and a disadvantage of using a turbine inlet pressure of 10 MPa compared to a turbine inlet pressure of 3.5 MPa. Refer to the quality of the steam leaving the turbine and the efficiency of the cycle.

In a Rankine cycle, 9.1 kg/min of steam enters the turbine at 2.5 MPa saturated and leaves at 50 kPa. If the pump and turbine efficiency i s72.7% and 80.8% respectively. @2.5 MPa hf = 962.11 kJ/kg sf = 2.5547 kJ/kg hg = 2803.1 kJ/kg sg = 6.2575 kJ/kg-k @50 kPa sf = 1.0910 kJ/kgK hf = 340.49 vf = 1.03 L/kg sfg = 6.5029 kJ/kg-k hfg = 2305.4 Find the following: a.) Net work of the actual cycle in kJ/hr PS. Input your answers in 5 decimal places. Show your unit analysis. SUBJECT: Thermodynamics 2
