Pipeline exploded as a result of
back pressure due to which water supply to Karachi city was suspended.
Back pressure is the resistance to exhaust gas flow out of the engine as occasioned by the atmosphere and the size of the exhaust pipe.
In a metering pump system, using a
back pressure valve alone does nothing to improve fluid flow.
In their study they have observed that Model 5 was the optimum design having 0.845 bar
back pressure and 12.5 m/s exhaust velocity.
For good landings, pilots need to have what I call a fine pitch control--not too much, not too little
back pressure. What is right is up to pilot/air plane combination.
The
back pressure of blood in the aorta against the heart's aortic semilunar valve is higher than that against the pulmonic semilunar valve of the pulmonary trunk.
Four parameters were measured to evaluate column performance throughout 8,300 injections: column
back pressure (Figure 3A), retention time of Allura Red AC (Figure 3B), peak shape of Allura Red AC (Figure 3C), and the resolution between the two food colorants (Figure 3D).
It features a new titanium exhaust system with larger diameter tailpipes, providing reduced
back pressure.
In-line valves feature low cracking pressure, which determines when the component starts to open; if
back pressure is a concern, choose from a variety of duckbill valves.
A robust
back pressure regulator provides precise C[O.sub.2] flow control.
When a U-Clip is placed on a shaft to hold a reel or core in place, the object being secured can create
back pressure against the clip.
