A computer calculates the gas flow based on pressure measurement made using a fixed orifice in the exhaust re-circulation system. Correction is applied for temperature and may also be applied for engine airflow and barometric pressure. The pressure downstream of a fixed orifice (205) located ...

And most important of all, it is easy to use, taking the pressure out of piping design, pipe flow calculations, and pipe pressure drop analysis. In short: Easy-To-Use, Reliable Calculations, Unrivalled Support, Unbeatable ValueYour excellent product is simply superb... let me say that I ...
A code for efficient and accurate gas pressure calculation named AVOCADO is described in this paper. The non-collisional gas flow is resolved at steady-state considering only the solid boundaries of the domain (gas–wall interaction), where the gas pressure is defined. The mutual interactions betw...
Because atmospheric pressure is relatively constant, the pressure in the lungs must change to create airflow between the lungs and the outside environment. During inhalation (inspiration), the diaphragm and supporting muscles (intercostal muscles) contract, which results in an expansion of the thoracic...
Elveflow's microfluidic calculator permits to calculate flow rate in microfluidics dependent upon the microfluidic system from the device, the tubing to your fluid properties.
Air Flow Calculation from Differential Pressure If you need to, you can calculate velocity from pressure in these problems if you are given enough information. Pressure differentials between locations are one means by which air is compelled to move from place to place, and the higher the pressure...
, PACO2is the partial pressure of carbon dioxide in the alveoli (which had to have come from within the body, as normal air actually has very little CO2) and K is a constant. Higher exercise rates imply more carbon dioxide produced as waste and a higher ventilatory excretion of the gas....
Steam Control Valves - Calculate Flow Factor Kv Designing steam control valves and their Kv values. The procedure below can be used for proper design of steam process control valves and their correct flow factors - Kv. 1. Determine Pressure Coefficient - Pcoef Start with the absolute pressure...
Calculate speed of efflux of kerosene from an orifice of a tank in which pressure is 4 atmosphere .Density of kerosene is 0.72 kg per litre .One atmosphere =
