A ruling pen is a drawing instrument for drawing with ink or with other drawing fluids. Originally used for technical drawings in engineering and cartography together with straight rulers and French curves , it is today used for specific uses, such as picture framing or calligraphy .

A technical pen is a specialized instrument used by an engineer, architect, or drafter to make lines of constant width for architectural, engineering, or technical ...
A pen is a handheld device used to apply ink to a surface, usually paper, for writing or drawing. [1] Additional types of specialized pens are used in specific types of applications and environments such as in artwork, electronics, digital scanning and spaceflight, and computing.
The pen has an ink container which contains a metal tube, inside which is a thin metal needle or wire, the soul. Ink is absorbed between the needle and the tube wall, preventing an excessive amount of ink from being released. The needle has a weight and by waving the pen back and forth the needle is released and the ink can run.
[7] [8] [9] Because of inertial effects, the fluid will prefer to the straight direction. Thus the flow rate of the straight pipe is greater than that of the vertical one. Furthermore, because the lower energy fluid in the boundary layer branches through the channels the higher energy fluid in the pipe centre remains in the pipe as shown in Fig. 4.
This approach was much simpler than other techniques tracking the surface of fluid, yet more versatile as it could model the coalescence and breakup of fluid regions. In 1976, Noh & Woodward [ 5 ] presented the Simple Line Interface Calculation (SLIC), a technique to approximate fluid interfaces based on volume fractions, designed for ...
Custody transfer requires an entire metering system that is designed and engineered for the application, not just flowmeters. Components of a custody transfer system typically include: Multiple meters/meter runs; Flow computers; Quality systems (gas chromatographs to measure energy content of natural gas and sampling systems for liquid);
Rapidly Attachable Fluid Transfer Interface (RAFTI) is a standard interface developed by Orbit Fab for transferring fluids, e.g., propellants, in space. [1] It has been defined by a group of 30 companies. The interface specification has high and low pressure variants, both for operation between -40 °C and 120 °C. [2]
