From the table above the discharge coefficient can be estimated to approximately 0.6 for a wide range of the Reynolds number. If the fluid is water with density 1000 kg/m3 and the pressure difference over the orifice is 20 kPa (20000 Pa, N/m2) - the mass flow through the pipe can be...
into 11.21 kPa and express the density as 1000 kg/m3 to solve for a new value of k: Q=kP1−P2ρ 180=k11.211000 k=18011.211000=1700 Nothing about the orifice plate’s geometry has changed from before, only the units of measurement we have chosen to work with. Now we possess a value...
that may cause the liquid to flash (convert to a gas) within the flow-meter If measuring a high viscosity liquid, confirm that the maximum flow-rate of the flow- meter has been appropriately de-rated so as to limit the maximum pressure drop across the meter to 100kPa (1bar, 14.5...

The instrument may also be configured to display measured gas pressure (kPa) using an external pressure transducer, and use this measured pressure to calculate pressure compensated (ppm(v), (ppm(w))SF6, g/m3 and g/kg. Dew points over the range -100°C to +80°C may be measured with ...

The spring-operated pressure relief valve seems to have been set arbitrarily at 20 kPa(g). Because of compression of the vapor head space during yeast slurry transfer, the normal operating pressure in the tank would be in the range of 10–20 kPa(g). The rupture disc seems to have been ...
