Question

Hi. I am trying to practice this problem using a checker online, but everytime I recalculate my answer it always says it's incorrect. So far I have calculated and tried to input the following values: 1 hp, 1.01 hp, and 0.8 hp but it always keeps saying they are incorrect. Am I missing a sign change? (Should the answer be negative?) Or am I solving this incorrectly and getting the wrong value each time? Please help show me the correct steps on how to get the correct answer as I am trying to learn this process. Thank you!

X Your answer is incorrect.
(Single pipe with pump) Without the pump shown in the figure below it is determined that the flowrate is too small. Determine the
horsepower added to the fluid if the pump causes the flowrate to be doubled. Assume that the friction factor remains at 0.025 in either
case.
