As you can see from the calculations of V max saturation occurs first for Chloride when 60 L of water has been treated. So if you don't want to have chloride in your water you have to stop the ion exchange system or if you have a duplex system you can switch to the other column available and regenerate the column that is saturated with the absorbed ions.

This reduction in pipeline head loss allows for the selection of a smaller pump that requires less ,power,. A larger pipe, however, costs more to purchase and build. The Crane Technical Paper 410 recommends a fluid velocity in the range of 5 to 10 feet per second (ft/sec) in a pump discharge pipeline, and a fluid velocity of 2.5 to 5 ft/sec on the pump suction pipeline when the fluid is water.

Irrigation Fundamentals – Water Well Journal

When calculating the ,pumping, head and head loss in a water system, unless you are developing or using a system head curve, it is important to use a uniform and single value of flow for the entire set of calculations. This is usually the highest projected flow rate anticipated, in gallons per minute (GPM).

Pump & Pumping Station Sizing Guide
Pump & Pumping Station Sizing Guide

To calculate - Take the overall lift and then for every 10m horizontal add another 0.5m to the lift. e.g: you have a run of 30m with a lift of 1.5m, this equates to 3.0m overall dynamic lift. Then look at the pump curve at 3m lift and see the flow. see the pump curve chart example below.
