Is there an EE around here that can help me with a problem? In my power systems class, one of my hw problems gives me the hp of a motor, the voltage, and the original power factor of the circuit, asking on what capacitor value I would need to correct the power factor to another value, but I can't for the life of me how to do it. I've been killing myself for about 2 hours now and I know it's simple, but I can't seem to piece it together. Anyone offer any help? Here is the question in all details, I even know the answer because it is in the back of the book, but I need to know how to "solve" it. Here it goes:

Problem:
A single-phase 3hp, 240V pool pump(motor) runs at full load with 92% efficientcy and a power factor of 0.73 lagging. Calculate the capacitor needed to improve the power factor to 0.98 lagging.
Thanks for the help!
