Question

The KWE tells us the instantaneous energy used at a point in time. To compute the total electricity consumed
(measured in kilowatt-hours), we need to multiply this instantaneous energy use by the duration for which it
is sustained. Since the data readings are made at 5-minute intervals, we will assume that this instantaneous
energy remains constant for that 5-minute period. We can then sum over these 5-minute periods to compute
the total electrical energy consumed over the one-month period that the data covers. You should compute
the result (displayed in megawatt-hours) separately for each chiller, as well as displaying the total. This tells
us approximately how much electricity was actually consumed during that period and will provide a baseline
for comparison when trying to improve the efficiency of the system.
