Matched Precipitation Rates (MPR)
Most of the large sprinkler manufacturer’s produce sprinkler heads with Matched Precipitation Rates (MPR). This simply means that all the heads will water at the same rate on a given sprinkler zone. To be more precise, it is the actual nozzle in the sprinkler head that will water at the same rate. So you could… Continue reading Matched Precipitation Rates (MPR)
Gallons Per Minute
In sprinkler systems, gallons per minute (gpm) or liters per second (L/s) is simply the volume of flow (how much) water is moving through your sprinkler system. If you are installing a new sprinkler system, maintaining your current system, or retro-fitting an existing system you need to know how many gallons per minute are available… Continue reading Gallons Per Minute
Flow, Velocity, & Friction Loss
