The pressure relationship between supervisors and those under their supervision
Thread Content
If the valve remains fully open and the pressure in the main cooling water pipeline is 2 bar, then is the circulating cooling water pressure at the inlet of the equipment on all branch pipelines also 2 bar? This is what I observed on site.
The original poster did not take into account the actual operating conditions; in production, due to the resistance of pipes and fittings, a pressure drop occurs, resulting in varying pressures in different areas.
That is, if pipeline friction losses are not taken into account, in an ideal situation, should the pressure readings shown on the main pipeline and the various branch pipelines be the same? ? Is this pressure value the static pressure energy in Bernoulli’s equation? ?
If frictional losses are not considered, and at the same height, the pressure in the main pipe and the branch pipes should be the same. I remember that static pressure energy is expressed as the product of pressure p and volume V, namely pV.
If frictional losses are not considered, and the pipes are not at the same height, are the pressures in the main pipe and the branch pipes equal? ? For example, if a branch pipe is 10 meters higher than the main pipe, will the pressure values be the same if pressure losses are not taken into account?
“If the valve remains fully open and the pressure in the main cooling water pipeline is 2 bar, then is the circulating cooling water pressure at the inlet of the equipment on all branch pipelines also 2 bar? The issue you mentioned occurs when the cooler return water valve is under control; that’s why the circulating cooling water pressure at the inlet of the equipment on all branch pipes is 2 bar.
