please answer quicky and show all work i will thumb up.

a power plant with a steam flow rate of 180 kg/s operates on an ideal rankine cycle

-the pump does 21kJ/kg of work

-the conditions at the inlet of the isentropic turbine are 8.0Mpa and 800C

- the condenser is at 40kPa and steam leaves it as a saturated liquid

a) determine the heat input to the steam in kJ/kg

b) determine the work done by the turbine in kJ/kg
