    Charger too big?

    My cell phone (Google Pixel 5) charges via USB-C charger with an output of 5v, 3a. Will it harm the battery to charge it from a USB-C Macbook Pro charger with an output of 5.2v, 3a?

    Affinity law question

    Back to basics here, I've got a pump on a VFD running at 60 Hz. It's moving 550 gpm with 90 ft. of head. If I slow this pump down until it moves only half the water, or 275 gpm, what will its head be? Thanks.
