Flow & the path of least resistance


Here's another Flint Hydraulics Tech Tip: If there is an alternate flow path for oil to take - a pressure relief valve, for example (not pictured, but situated upstream of the gauge & faucet) - and if the pressure caused by the resistance of the partially closed faucet rises to the pressure setting of the relief valve, then part of the flow from the pump will flow through the faucet, and the rest through the relief valve. If the pressures across the two flow paths are equal, then flow will be split evenly. Half the flow rate will go through the faucet, half through the relief valve.

Resistance to flow

Here's another Flint Hydraulics Tech Tip: If a faucet is partially closed, it resists flow by forcing all the flow to pass through a smaller opening. A gauge upstream of the faucet inlet will show an increase of pressure. Closing the faucet a bit will not necessarily reduce the flow rate out of the faucet. If there is no other flow path, the pressure will rise to the level required to push the full flow rate through the smaller opening. Need help troubleshooting?
