PROBLEM:

A Rankine cycle is executed with steam expanding initially from $20$ MPaa and $100$ deg SH $.$

Condensation occurs at $T=86\mathrm{.}49$ degree Celsius. All expansion and compression efficiencies are $90\%$;

generator efficiency $=95\%,$ brake engine efficiency $=90\%.$ Turbogen speed $=1200rpm.$ Sketch the

equipment layout and the TS diagram.

Answer the following for $m=10k\frac{g}{sec}$ of steam circulated and fill up the blanks in the items below:

Equipment Layout and TS diagram with the cycle showing correct location of points with respect

to saturation dome line with $ne$ and $nc=90\%.($Show in your solution sheets.$)$

What is the power measured at the turbine shaft by the dynamometer in KW if shaft is rotating

at $1200$ rpm $?$ Answer:

Ideal Steam Rate for the engine in $K\frac{g}{K}W-hr$ Answer:

Heat rejected at the condenser in KW $($Actual$)$ Answer:

Actual Rankine engine efficiency $(\%)$ Answer:

Torque measured at the turbine shaft in KJ$.$ Answer:

Ideal Rankine cycle efficiency using Qa and Qr values $\%$ Answer:

Actual Rankine cycle efficiency using Turbine work and Pump Work values $\%$ Answer:

Using enthalpy of cooling water that enters the condenser at $12$ deg C and leaves at $21$ deg C $,$

find amount of cooling water needed by the condenser in $k\frac{g}{sec}.($Ideal$)$

Answer:

Combined heat rate in $K\frac{J}{K}W-$h$$
