2010/5/1· In fact, to develop 125 gpm at 200 psi (a typical 300-foot 1-1/2-inch attack line), a single-stage pump will need to spin faster than it would to pump 1,500 gpm at 150 psi. At this speed, the impeller wants to flow in excess of 1,500 gpm. But the nozzle at the end of
In a supersonic nozzle, the narrowest section is described as critical. The relative velocity v a /a in the discharge area of a supersonic nozzle depends only on the ratio of the discharge area F a to the area of the critical section F a and, within wide limits, is independent of variations in the pressure p 0 in the front of the nozzle. . Consequently, by varying the area of the critical
2013/12/16· discharge as described in 112.1(b)). ^Appropriate containment _ must be designed to address the most likely quantity of oil that would be discharged from the primary containment system (e.g., container, 79 Onshore components associated with offshore
Discharge Static Head: The difference in elevation between the liquid level of the discharge tank if the pipe end is submerged and the centerline of the pump. If the discharge pipe end is open to atmosphere than it is the difference between the pipe end elevation and the suction tank fluid surface elevation.
The jet fluid was pumped to the jet nozzle by a submersible pump, and a rotameter was used to adjust and monitor the rate of discharge. Experimental investigation of Elliptical jet in coflow This system is improved from its predecessors by using a floating jet nozzle to propel the hose downstream instead of floating a tag line with flow.
To fully understand pipe class and piping specifiion you must know the basics of the piping. Pipe covers a very large part of any process plant. If you look at the Oil Exploration platform, Refinery and Petrochemical complex one thing that ches the attention is a
Hydraulics is confusing and often what seems logical isn''t how it really works. This Q&A examines pipe size and why bigger is almost always better. Q. I’m designing a pump system from a lake and have read and understand your calculation of FT HD needed for
When you pull the trigger on your pressure washer, if the water pressure is good for a moment but then weakens, you have a surging issue. A few factors could be causing this problem. Generally, this means that the flow rate required by the pump cannot be
Extinction Rebellion is a loosely networked, decentralised, grassroots movement. Anyone who takes action in pursuit of "XR''s three goals and adheres to its ten principles, which includes non-violence, can claim to do it in the name of XR." The Economist identified the group as using the tenets of holacracy to operate more effectively given strong state opposition.

EPA promulgated the Oil and Gas Extraction Effluent Guidelines and Standards (40 CFR Part 435) in 1979, and amended the regulations in 1993, 1996, 2001 and 2016.The regulations cover wastewater discharges from field exploration, drilling, production, well treatment and well completion activities.
Apart from sprinkler system, other fire service installations e.g. fire alarm, hose reel system, heat/smoke detectors, extinguishers, etc. shall also not be obstructed by obstacles and should be properly maintained for ready use in case of fire.

For silo design, additional local pressure which depends on eccentricity of discharge outlet, and equations which give approximate stress produced by this pressure are given in this 2010 publiion. August 2011 Sub-committee for Design of Storage Tanks
In fact, NPSH-R is defined as the suction-side pressure at which cavitation reduces the discharge pressure by 3%. So, in designing the suction-side pipework for your system, you must ensure that it exceeds the manufacturer’s NPSH-R rating for the operating conditions.
Static Ignition Hazards When Handling Petroleum Products Sullivan (Sully) D. Curran PE, Executive Director Introduction Static electricity in one form or another is a phenomenon of nature and often results in electrostatic discharges that can cause fires and

Fixed or Semi-Fixed Fire Protection Systems for Storage Tanks In the early years of the oil industry, fire in a storage tank was a common occurrence. Virtually all products were stored in cone roof tanks built of riveted steel plates and the roof was often constructed
A primer will pump a small amount of gas into the carburetor. Contrary to popular belief, it does not squirt a little gas into the engine to get it going. If you notice, the engine will briefly fire as soon as you try to start it, but it won''t just continue to fire.
GUIDELINES FOR THE CONTROL OF STATIC ELECTRICITY IN INDUSTRY 4 ARCHIVE 1. INTRODUCTION 1.1 Static electricity is generated by the contact and separation of materials, and clearly this generation often cannot be prevented in the industrial setting.
In this definition, “control” means the power to direct the management and policies of an entity, directly or indirectly, whether through the ownership of voting securities, by contract, or otherwise. (b) “API” means American Petroleum Institute.
System (1) for manufacturing containers by blow moulding, the system (1) comprising: a mould (2) comprising a wall defining a mould cavity and having a conduit for carrying a heat-transfer fluid, this conduit having on an outside face (12) of the mould (2) a heat-transfer fluid inlet port and a heat-transfer fluid outlet port; a fitting (20) having a heat-transfer fluid admission line, and a
Siphon definition is - a tube bent to form two legs of unequal length by which a liquid can be transferred to a lower level over an intermediate elevation by the pressure of the atmosphere in forcing the liquid up the shorter branch of the tube immersed in it while the
FLOW IN PIPES Fluid flow in circular and noncircular pipes is commonly encountered in practice. The hot and cold water that we use in our homes is pumped through pipes. Water in a city is distributed by extensive piping net-works. Oil and natural gas are
