Thousand pounds per square inch

A constant, reproducible flow rate on the order of 3-10 ml min at a pressure of several thousand pounds per square inch makes the pump the most... 

Most high-performance liquid chromatography (HPLC) pumps can be used in HOPC. The back pressure rating should be at least several thousand pounds per square inch (a few hundred kg/cm ). A type of pump that does not allow bypassing the pressure transducer or a pulse damper, if it is installed, must not be used. The dead volume should be as small as possible. Pumps with a single plunger are better than those with two plungers. 

Columns need to withstand a pressure of at least several thousand pounds per square inch. Stainless-steel columns are recommended. 

As evidence of light guide fiber stabilization and control through processing refinement, plot of frequency of failure against the tensile strength (in hundreds of thousands pounds per square inch) shows extraordinary uniformity for the control system compared to wide distribution of failures from surface defects and other variations in a conventional fiber... 

Safety concerns are associated with the flammability and, sometimes, toxic properties of transported products, the high pipeline pressures (hundreds of pounds to over a thousand pounds per square inch), and the proximity to population or environmentally sensitive areas at some locations along the rights-of-way. 

A typical detonator has three sections, the first containing a (nondetonating) "primer" the initiator, lead or silver azide, is in the second section and finally, a secondary explosive forms the third section. Normally, each of the sections is filled or "loaded" by pressing the explosive into a metal sleeve or cup under pressures of several thousand pounds per square inch. The next component or element in an explosive train is an acceptor charge, containing a secondary explosive or "lead" the output Irom the secondary in the detonator is required to initiate the "lead" reliably (secondary explosive acceptor). 

Tensile properties were measured using ASTM D-638. Msi, million pounds per square inch ksi, thousand pounds per square inch. 

Whatever means is used to secure the molten polymer, it is moved forward to a gear-type pump that provides both high pressure and a constant rate of flow to the final filter and spinnerette. The filter consists of either sintered metal candle filters, several metal screens of increasing fineness, or graded sand arranged in such a way that the finest sand is at the bottom. After being filtered, the molten polymer at a pressure of several thousand pounds per square inch is extruded through the small capillaries in the heavily...
