In the Solution to Pump Challenge #3, we touched on efficiency and energy savings by approximating energy costs. Can we do this more precisely?

Pump Challenge #4 asks that you evaluate energy saved from efficiency more accurately. Using the same set of conditions (4,000 gpm and 400 feet) at the same two speeds, find out the difference in energy consumption by clicking here for the Energy Savings Evaluator Program.

What is your answer in power and yearly investment? The respondent with the best answer receives a winning ticket to an upcoming Pump School class.
