Q2: Consider a reheat cycle utilizing steam. Steam leaves the boiler and enters the 450C. After expansion in the turbine to 300 kPa, the steam is reheated to 400C and t low pressure turbine to 4 kPa. a. Determine the cycle efficiency b. What is the difference between Carnot and Rankine cycle and how efficiency c improved? explain superheat PMPa TC h S 5 450 3317.2 6.8210 0.3 400 3275.5 8.0347 saturated P kPa Tsat C hf hfg hg sf 300 133.52 561.43 2163.5 2724.9 1.6717 4 28.96 121.39 2432.3 2553.7 0.422
