In order to choose the best flow meter, you have to evaluate flow rate, flow velocity, and pipe diameter data. But with only ⅔ of the necessary data you can still figure out the last ⅓ using the chart below. For example, if you know flow rate and pipe size, the chart can guide you to calculate the flow velocity.

13-01-2011· "Because dilute phase systems are relatively simple, the upfront investment costs are very economical compared to dense phase," said Shawn Werner, chief engineer at Vortex Valves. It gets better. "Almost any material can be conveyed in dilute phase suspension flow through a pipeline, regardless of the particle size, shape or density," said Paul Solt of Pneumatic Conveying Consultants.

In Pipeline Rules of Thumb Handbook (Eighth Edition), 2014. Example 2. If pipe diameter is to be determined for the desired pressure drop and the known length of line, flow rate, and the properties of fluids, then the problem cannot be solved directly. The procedure is as follows: An estimate is made of the diameter of the two-phase line. The best approach is to determine, for the conditions ...

pipeline and an air supply to the start of the conveying pipeline of 216 fV/min of free air (scfrn). In both cases the air velocity at the pick-up point is 1500 ft/min and the conveying line pressure drop is 10 Ibf/irr. At this low velocity, it is clear that the mode of flow would be dense phase. In …

sure below 15 psig, dense-phase conveying lines operator above 15 psig. Also, dilute-phase conveying lines can be operated over a much longer distance than dense-phase conveying lines. Due to gas com-pressibility and impractical pres - sure drops, dense-phase convey-ing lines longer than 500 yards are rare. The design and operation of a

Pipe Flow Calculator (API RP 14E criteria). APIpe calculates the minimum internal diameter and wall thickness for a pipeline transporting single and multi-phase hydrocarbon fluids according to the recommended practice (API RP 14E; §18) issued by the offshore industry's most prominent authority: the API. APIpe calculates the performance criteria for liquids, gases and a combination of the two ...

21-11-2017· This equation is usually adapted for two-phase flow by assuming that the two-phase flow regime and two-phase properties can be considered homogeneous over a finite volume of the pipe. Many correlations have been developed for predicting two-phase flow pressure gradients which differ in the manner used to calculate the three terms of pressure gradients equation (elevation change, …

03-02-2021· The hydraulic radius, R, is the proportion between the area and the perimeter of your pipe. If the pipe is circular, you will find it according to the following equation: R = A / P = πr² / 2πr = r / 2 = d / 4. where r is the pipe radius, and d is the pipe diameter. You can view and modify all these parameters (area, perimeter, hydraulic radius) in the advanced mode of this pipe flow calculator.

The pipe flow calculation can compute flow rate, velocity, pipe diameter, elevation difference, pressure difference, pipe length, minor loss coefficient, and pump head (total dynamic head). The density and viscosity of a variety of liquids and gases are coded into the pipe flow program, but you can alternatively select "User defined fluid" and enter the density and viscosity for fluids not listed.
