Question 1 35 pts Water is the circulating fluid in an ideal Rankine cycle. Saturated vapor enters the turbine at 16 MPa, and the condenser pressure is 8 kPa. Table provides the enthalpy values for the four stages of the Rankine cycle. The mass flow rate of steam entering the turbine is 100 kg/s. State 1 12 3 h [kJ/kg] 2600 1650 175 200 (a) Draw a T-s diagram showing the cycle. (6 points) Using the given values, determine (i) the net power developed, in kW. (8 points) (ii) the rate of heat transfer to the steam passing through the boiler, in kW. (8 points) (iii) the thermal efficiency (5 points) and (iv) the mass flow rate of condenser cooling water, in kg/s, if the cooling water undergoes a temperature increase of 18C with negligible pressure change in passing through the condenser. (8 points) (Watch "Ideal Rankine Cycle- Example")
