All changes in kinetic and potential energy may be ignored. All pressure losses due to friction may be neglected. Ideal conditions must be assumed where necessary. Do the calculations needed to find the pressure at this point. Choose the closest value that will reduce the amount of interpolation needed. 1.1. Find the pressure (kPa) and temperature (K) at Points 1 to 7.. Assume ideal conditions where necessary. ASSUMPTIONS made at each point MUST be STATED clearly at the specific point. 1.2. Find the enthalpy at Points 8 to 15 (kJ/kg), Pump work must be included. Assume ideal conditions where necessary. ASSUMPTIONS made at each point MUST be STATED clearly at the specific point. 1.3. Calculate the mass flow rate of the steam at Point 10 in kg/min. ENERGY BALANCES must be SHOWN. 1.4. Calculate the nett work output available from the Rankine cycle in kJ/kg. ENERGY BALANCES must be SHOWN.
