The input-output curve of a 60 MW power station is provided by :
I = 10^{6}[8 + 8L + 0.4L^{2}] Kcl/hour
where I is the input in the Kcal/hour and L is the load in MW.
(a) Evaluate the heat input per day to the power station if it works for 20 hours at full load and remaining period at no load.
(b) Determine the saving per KWh of energy produced if the plant works at full load for all 24 hours creating the same amount of energy.
