A hydroelectric generating plant is characterized by the following input-
output characteristic
q = 250 + 6PH acre-ft/hour
100 MW PH 1000 MW
where q is the water ow rate through the plant and PH is the output power in
MW.
The plant supplies the following electrical loads over a 4 hour period:
Hour 1 600 MW
Hour 2 800 MW
Hour 3 1000 MW
Hour 4 500 MW
How many acre-ft of water are used to supply the load over the 4 hour period?
