Tgrief: I should have clarified that I'm interested to learn to do p+id's for simple domestic water pump stations, say with 1 duty and 1 standby pump where we're monitoring suction and discharge pressure, flow rate, pump speed and have a timed delay on pump start up after shut down.
KRS: Thanks...
Gere's my scenario: Water transfer pump. Static head on the system is about 395 feet, which we're pumping (VFD) against to deliver water to a tank some 1.4 miles away. Using a GA Industries 4" surge relief valve, low velocity of 5 fps (1650 usgpm), to be set to discharge to waste (may...
Having read the above, I now submit my scenario: Static head on the system is about 395 feet, which we're pumping (VFD) against to deliver water to a tank some 1.4 miles away. Using a GA Industries 4" surge relief valve, low velocity of 5 fps (1650 usgpm), to be set to discharge to waste...
Anyone have any resources on the above? My goal is to learn how to do p+ids for pumping stations, water treatment plant, etc. Thanks (also posted in water treatment discussion)
The main reason I wanted it is because I often start a spreadsheet, get interrupted and when it comes time to close Excel for the day, I'm asked if I want to save my changes. If I know the last revision time it sometimes makes it easier to decide whether or not to save the changes.
