! Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. The net work output and the thermal efficiency for the Carnot and the simple ideal Rankine cycles with steam as the working fluid are to be calculated and compared. Steam enters the turbine in both cases at 5 MPa as a saturated vapor, and the condenser pressure is 50 kPa. In the Rankine cycle, the condenser exit state is saturated liquid and, in the Carnot cycle, the boiler inlet state is saturated liquid. Draw the T-s diagrams for both cycles. (Please upload your response/solution using the controls below. You must provide an answer before moving on to the next part.)
in a regenerative cycle the inlet conditions are 40 bar and 400°C. Steam is Bleed at 10 bars in regenerative heating. The exit pressure is 0,8 bars. Neglecting Pump work; determine the efficiency of the cycle
Design a "Reheat Rankine Ideal Cycle" with the following requirements:1. Set your boiler's pressure and temperature.2. Set your condenser's pressure.3. Solve your design's "Rankine Ideal Cycle" and get the thermal efficiency.4. To maximize efficiency, add a reheater to your initial setup.
A 60 MW power plant operates with a reheat cycle. The steam enters the turbine at 15 MPa, 590°C. The steam enters the reheater at 1.95 MPa and 280°C and exits at 1.8 MPa, 590°C. Conden pressure is. 0.0035 MPa. The steam rate is 150.000 kg/hr, and the generator efficiency is 90%. Determine the following: 1. Ideal cycle thermal efficiency without pressure drop 2. Actual cycle thermal efficiency 3. Actual combined engine efficiency 4. Enthalpy of exhaust steam (at point 4) if the heat lost through the turbine casing is 2% of the combined work.
4) In a reheat Rankine cycle, water vapor enters the high-pressure turbine at 9MPa and 450°C. It is expanded to an intermediate pressure of 0.8MPa and enters the low-pressure turbine with a temperature of 400°C. Condenser pressure is 7.5kPa and water enters the pump as a saturated liquid. There is no pressure loss in the piping that connects the cycle components. Water mass flow rate is 60 kg/s and both turbines have an isentropic efficiency of 90%.

My Question: In the steam plant problem#2, the reheater developed a leak and it was decided to run the plant bypassing the reheater. Determine the thermal efficiency and steam flow rate to develop the same power output.Problem 2 (In a reheat cycle steam enters the high-pressure turbine at 40 bar and 400C. It expands isentropically to 6 bar and is reheated at constant pressure to 400C. This steam is expanded isentropically in the low pressure turbine to the condenser pressure of 0.1 bar. Calculate the thermal efficiency and steam consumption for 10 MW output.)
