In a steam power plant, superheated steam at 673 K and 2 MPa enters the turbine and it is expanded to the condenser pressure of 7.5 kPa . Assuming an isentropic pump efficiency of \( 85 \% \) and an isentropic turbine efficiency of \( 90 \% \), calculate the following : (i) The ideal Rankine cycle efficiency for the given conditions (ii) The thermal efficiency of the plant Additional data : The specific volume of saturated liquid at 7.5 kPa is \( 1.008 \times 10^{-3} \mathrm{~m}^{3} / \mathrm{kg} \).
