2.2 Meeting Power Demand
2.2 Meeting power demand
The figure and table below show the how power demand at Folsom varies over the course of a year. You should notice that power demand is highest during summer months (May - July) and the reservoir is also most full (highest head) during these same months.

Using the power equation below calculate the average discharge needed to meet the power demand in every month. Fill in the missing variables in each cell of the table below. After checking that you've entered the correct values, the table will calculate the requisite discharge and display a graph of monthly power demand, discharge and head.
Q = (P * 1.181 * 10^4)/(η H)
