In ideal constant volume cycle, the pressure and temperature at the beginning of compression are \(97 \mathrm{kPa}\) and \(50^{\circ} \mathrm{C}\), respectively. The volume ratio is 8. The heat is supplied during the cycle is 930 \(\mathrm{kJ} / \mathrm{kg}\) of working fluid. Calculate: (i) the maximum temperature attained in the cycle, (ii) the thermal efficiency of the cycle, and (iii) work done during the cycle/kg of working fluid.
