simple Rankine cycle uses water as the working fluid. Water enters the pump as a saturated liquid at 10 kPa and exits at a pressure of 5 MPa. Water enters the condenser as a saturated mixture with a quality of 90%. Assume that the cycle is ideal. 1. What is the temperature of the turbine inlet, in °C? Report your result to one decimal place using rounding. 2. How much heat was added in the boiler, in kJ/kg. Round to the nearest wh

The engine on a steam ship runs on the Rankine cycle. The steam leaves the boiler at 20 bar and 350°C. The turbine has an efficiency of 75% and an outlet pressure of 1 bar. The pressure changes in the boiler and condenser can be considered negligible, and the liquid leaving the condenser is saturated. A. Determine the operating temperature of the condenser, and compute the efficiency of a Carnot cycle operating between the boiler and condenser temperatures. B. Determine the actual efficiency of this Rankine cycle and compare it to the Carnot efficiency. C. When the Titanic was sinking, the Carpathia received the S.O.S. and immediately set course to attempt a rescue. The captain of the Carpathia ordered the hot water turned off in the passengers’ cabins (Lord, 1955). What effect do you expect this action had?

Problem 2: Consider the following Rankine cycle with reheat (notice the numbering here is different from the previous diagram). Steam enters the high pressure turbine at 14MPa and 600C, and is reheated at constant pressure to 600C. It exits the second, low pressure turbine at 10kPa with a quality of 89.4%. Given 2 1 3 4 P3 = 14MPa T3 = 600°C 5 T5 = 600°C Condenser High P. 6 Low P. PG = 10kPa x6 = 89.6% (i.e. moisture content Is limited to 10.4%) Find P4, nth Assumptions SS, Ake = Ape = 0 Ideal cycle (isentropic efficiency of turbine and pump are 100%, no heat transfer where unintended, no pressure drops due to friction) P₂ = P3, P4 = P5, P6 = P₁

In a steam power cycle, the steam supply is at 15 bar and in a dry and saturated condition.The condenser pressure is 0.4 bar. Calculate the Carnot and Rankine efficiencies of the cycle.Ignore the work of the pump.
