Answer»

A steam power plant working on Carnot cycle operates between $320^{\circ} C$ , 10 Mpa and $31^{\circ} C$ and 6 kpa. The following data table is available

P	$T (^{\circ} C)$	$h_{f} (k J / k g)$	$h_{g} (k J / k g)$	$s_{f} (k J / k g K)$	$s_{g} (k J / k g K)$
10 MPa	$320^{\circ} C$	1407	2725	3.35	5.61
6kPa	$31^{\circ} C$	136	2560	0.48	8.40

Back work ratio of the cycle is ______.

0.37
