There's something wrong with the way you have your script in your calculator. That friction factor makes no sense for the givens. It should be somewhere around 0.022, confirmed by manually calculating it with the given expression and checking against a Moody Diagram
the actual work from the pump that you calculated is wrong. you’re supposed to multiply the efficiency by the ideal work to get the actual work. you divided them.
this video is PURE GOLD! Thank you soo much!!

No, mechanical power must be greater than water power. So it must be divided.
