Chapter 9, Problem 9.80P

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

Write a note on the combined cycle power plant. Please include practical example, narrating the capacity of different components.

In an ideal Rankine Cycle, steam at 5 MPa and 500 °C enters the turbine and after expansion exits as saturated vapor. For 110,000 kg/hr of sream, find: a) Ideal power output of the Turbine (kW), b) Power to drive the pump (kW), c) Rate of Heat Added (kW), d) thermal efficiency of cycle and engine, e) steam rate of the cycle and engine, f) Heat Rate

IDEAL RANKINE CYCLE: In an ideal Rankine Cycle, steam at 5 MPaa and 500 o C enters the turbine and expands 300 KPaa. For 110,000 kg/hr of sream, find: a) Ideal power output of the Turbine (kW), b) Power to drive the pump (kW), c) Rate of Heat Added (kW), d) thermal efficiency of cycle and engine, e) steam rate of the cycle and engine, f) Heat Rate (PLEASE SHOW COMPLETE SOLUTION AND ENCLOSED ALL THE FINAL ANSWERS ROUNDED OFF TO THE 4TH DECIMAL)

On my online homework, it says the answer for part b, 993.2 kW and part c, 360.06 are incorrect. I also need help with part d.   The figure below provides steady-state operating data for a cogeneration cycle that generates electricity and provides heat for campus buildings. Steam at 1.5 MPa, 280°C, enters a two-stage turbine with a mass flow rate of m1 = 2 kg/s. A fraction of the total flow, y = 0.15, is extracted between the two stages at 0.2 MPa to provide for building heating, and the remainder expands through the second stage to the condenser pressure of 0.1 bar. Condensate returns from the campus buildings at 0.1 MPa, 60°C and passes through a trap into the condenser, where it is reunited with the main feedwater flow. Saturated liquid leaves the condenser at 0.1 bar.

USE THE GIVEN BELOW.In a simple Rankine cycle, the steam throttled condition is 8 MPa and 480°C. The steam is then reheated to 2 MPa and 460 °C. If turbine exhaust is 60 °C, determine the following: a. Heat Added   b. Turbine Work   c. Heat Rejected   d. Pump Work   e. Net Work   f.EfEfficiency
