OH 86: HVAC: Systems And Components #10
Q: Why couldn't we use pump affinity laws here to find the ratio of W HP2 over W HP1?
A: By doing that ratio equals to the ratio of the motor speed, or against the pump speed cube. And then finding the speed ratio equals square root of total dynamic head ratio. This gives us a ratio for the power of 0.818.
