ANSI B1.20.1 - NPT - American National Standard Taper Pipe

1) The taper rate is 1 in 16 inch (3/4 inch in a foot or 62.5 mm in a meter) TPI = threads per inch; 1 inch = 25.4 mm; NPT threads are not interchangeable with NPS - National Pipe Straight - threads. Example - Typical Designation of NPT thread: 1⁄8–27 NPT; NPT threads may look similar to ISO 7-1 threads. However, ISO and NPT threads should

Thread Standards | Tameson

Specifically speaking, at 1/16, 1/8, 1/4and 3/8 sizes, pitch difference results in misalignment of the threads. This misalignment might result in the threads to be fastened only partially. However, at 1/2 and 3/4 sizes, NPT and BSP have the same pitch which will allow them to engage well. Nevertheless, since there are differences in thread forms and thread angles, there will still be …

Pipeline Pressure Loss Calculators

The first form calculates the pressure or friction loss along a given length of pipeline with a specified inside diameter. The second form calculates the minimum pipe size to limit pressure loss to a specified value. Additional friction pressure losses occur due to fittings. These losses in-effect add extra additional length to the total pipeline.

Pressure Loss Due to Fluid Flow Through Pipes - Womack

Example: For a flow of 50 GPM through a tube of 1½˝ O.D. with 0.095 wall, use the 1 ¼ ˝ pipe size under 50 GPM in Table 1. This shows a 15 PSI loss per 100 feet. Multiply this times 0.981 from This shows a 15 PSI loss per 100 feet.

Acid Digestion - an overview | ScienceDirect Topics

The first two dissociations of pyrophosphoric acid (K 1 = 1.4×10 −1, K 2 = 1.1×10 −2) are both stronger than the first dissociation of orthophosphoric (K 1 = 7.11×10 −3). Orthophosphoric acid probably therefore plays little part in the reactions given in [4-5.6a, b]. The addition of water perturbs the equilibrium by creating an excess of orthophosphoric acid and triggers a long, …
