Your colleague at the power plant station initiated a mutual discussion, where he suggested applying the Carnot cycle since it is considered the optimal cycle that steam power plant may be operated on. You were in a position to justify him why there many difficulties and impracticalities associated with the Carnot cycle in terms of the steam power plant, deliver a brief report explain why the Rankine cycle is preferred over the Carnot cycle in steam production plants, mention all impracticalities associated with applying Carnot cycle including the limitation of boiler and condenser temperature and pressure with respect to the surrounding saturation conditions (you may construct TS diagrams for both cycles to demonstrate your comparison).

I don't know how to do this engineering problem. Need help! This is the complete problem. PLEASE DO NOT REJECT. I had other experts on bartleby help me with problems similar to this one.   A regenerative vapor power cycle with two feedwater heaters, a closed one and an open one is shown in Figure 1. Steam enters the first turbine at 14 MPa, 520°C, and expands to 1.0 MPa. Some steam is extracted at 1.0 MPa and fed to the closed feedwater heater. The remainder expands through the second-stage turbine to 300 kPa, where an additional amount is extracted and fed into the open feedwater heater operating at 0.3 MPa. The steam, expanding through the third-stage, exits at the condenser pressure of 10 kPa. The two outputs from the feedwater both leave at 210°C. Assume the 12 MPa liquid in State 9 has an enthalpy approximately equal to saturated water at 210°C. The condensate exiting as saturated liquid at 1.0 MPa is trapped into the open feedwater heater and throttled into the open heater.…

In a steam power plant operating on ideal Rankine cycle, steam enters the turbine at 20 bar with an enthalpy of 3384 kJ/kg and an entropy of 7.127 kJ/kg K. The condenser pressure is 0.1 bar. Find the cycle efficiency, Work ratio and specific steam consumption in kg/kWh. Do not neglect pump work. You may make use of the extract of steam table given below. t hg St Sg (bar) (°C) kJ/kg kJ/kg 20.0 212.4 908.8 1890.7 2.447 6.331 0.1 45.81 191.83 2584.7 0.6493 8.1502

Could subsection Vii and onwards be solved please?

The ideal Rankine cycle is used for the production of energy in a power plant. Some of the conditions in the cycle are as follows: Condenser Exit: 6 psia, Saturated liquid Pump Exit: 500 psia Work Needed by the Pump: 2.4 Btu/lbm Turbine Inlet: 1200 °F Calculate the work produced by the turbine and draw a T-s diagram of the cycle including relevant properties and saturation lines.

(a) Steam is supplied, dry saturated at 40 bar to a turbine and the condenser pressure is 0.035 bar. If the plant operates on the Rankine cycle, calculate, per kilogram of steam: (i) the work output neglecting the feed-pump work; (ii) the work required for the feed pump: (iii) the heat transferred to the condenser cooling water, and the amount of cooling water required through the condenser if the temperature rise of the water is assumed to be 5.5 K; (iv) the heat supplied; (v) the Rankine efficiency; (vi) the specific steam consumption. (b) For the same steam conditions calculate the efficiency and the specific steam consumption for a Carnot cycle operating with wet steam.   (C) Repeat Problem (a) for a steam supply condition of 40 bar and 350 °C and the same condenser pressure of 0.035 bar.

A closed-cycle gas turbine unit operating with maximum and minimum temperature of 760 ⁰C and 20 ⁰C has a pressure ratio of 7/1. Calculate the ideal cycle efficiency and the work ratio. (Hint; This problem is on closed cycle gas turbine).

At the entrance to the turbine, the temperature is 450 °C. The isentropic efficiency of the turbine is 90%, pressure and pump losses are negligible, and the water leaving the condenser is subcooled by 9.6 °C.

I need help on this assignment: Exhaust gases from the turbine of a simple Brayton cycle are quite hot and may be used for other thermal purposes. One proposed use is generating saturated steam at 110℃ from water at 30℃ in a boiler. This steam will be distributed to several buildings on a university campus for space heating. A Brayton cycle with a pressure ration of 6 is to be used for this purpose. Plot the following:(a) The mechanical power produced,(b) the flow rate of the produced steam,(c) the maximum cycle temperature, all as functions of the rate at which heat is added to the cycle.
