    HVDC - Current Source Converter - Minimum DC Power flow

    Hello, I was reading about the differences between Current Source Converters and Voltage source converters. One main difference was that Current source converters need to have a minimum DC power flow of 5-10% while VSC do not have a min flow requirement. It was also called a deadband. Why is...

    Calculate Horsepower for Pumping Water from 50m Depth at 10m/s Flow Rate

    Hi, I calculated the Potential energy(work done)= 2*9.81*50=981 Js-1 Kinetic energy=mv^2/2= 2*100/2=100 Js^-1. But how do you calculate using thees, the horsepower...or at least in Joules cause then converting into horsepower is easy. Thanks.
