New in SF Pressure Drop 6.25 (May 1, 2018)
- New element "Dynamic pressure change":
- In enlarging or contracting pipes the following pressure changes are existing:
- 1. Pressure drop caused by friction, turbulences and flow separation:
- dP = resistance coefficient x density/2 x velocity²
- 2. Pressure change caused by changes of kinetic energy acc. Bernoulli formula:
- dP = density * (velocity1² - velocity2²)/2.
- For enlargements the pressure change is positiv, for contractions negativ.
- The element "Dyn. pressure change" calculates the static pressure changes caused by changes of kinetic energy. Normally you input the dimension of begin and end of the whole pipe.
- Attention: The calculated data are output as pressure drop, i.e. if the output is negativ the pressure is encreasing, if the output is positiv the pressure is decreasing.
- In previous program versions (< version 6.25) these pressure changes were calculated in combination with pipe enlargements and contractions.
