Chapter 9, Problem 9.1P

Find the Rankine cycle thermal efficiency of a steam plant with the following enthalpies in KJ/kg: entering turbine: 3100, leaving turbine= 2400, entering pump= 140 leaving pump= 180.

Why does intercooling reduce work in a comprssor (such as in the Brayton cycle), but it doesn't affect work in a pump (such as in the Rankine cycle)?

Provide the given, manual step by step solution, and diagram.  A Carnot cycle has an efficiency of 60 %. The heat added is 1000 KJ.What is the heat rejected from the cycle?

Classify the gas turbines based on working principle? Explain any one system in detail with diagram?

In a simple Rankine cycle, steam enters the turbine in superheated state. It is shown in the below diagram. T 1 4 (3 S The properties of the state of the steam is given in a table.

c) Some cars have petrol engines and some cars have diesel engines, but no car ever uses a Carnot engine. Compare the the efficiency of the Diesel and Carnot cycle and explain the reason to opt for a Diesel cycle instead of a Carnot cycle.

for a rankine cycle, steam at 5.25 MPa. 435 degree celcius expands to 0.036 MPa. For 10kg/s of steam, determine heat added, heat rejected, work of turbine, thermal efficiency

1. A medium size power station is used to produce 30 MW net power for a refinery. The station uses steam as the operating fluid and operates according to the Carnot cycle between the pressure limits of 0.4 bar and 35 bar. Steam enters the boiler as a saturated liquid and leaves it as a dry saturated vapour. (i) List the name of the four processes in a generic Carnot cycle and state what type of energy transfer (work/heat) can be neglected in each process. (ii) Sketch a T-s diagram for the above cycle indicating the location of the four components required. (iii) Determine the dryness fraction of the steam that is fed to the condenser.

Write the expression for efficiency of a Rankine cycle in terms of Wturb, Wpump, Qin, Qout, and enthalpies.   Thermodynamics question  briefly explanation please
