Vacuum Pumping Speed per. ISO 21360-1 Formulas
Vacuum pump performance is rated in terms of throughput, pumping speed, and vacuum pressure capability. They are rated for either intermittent or continuous duty.
Aerodynamics Airfoil Theory Equations
The lift coefficient can be approximated by the equation, The drag coefficient may be approximated by
Wind Force Scales Beaufort Wind Scale, Saffir-Simpson Wind Scale, Fujita Wind Scale
Wind Force Scales: Beaufort Wind Scale, Saffir-Simpson Wind Scale, Fujita Wind Scale
Wet Bulb Temperature Equation
The wet-bulb temperature, Twet, is a common humidity variable (e.g., Schwerdtfeger 1976, p 50ff.). A wetted thermometer will read lower than the ambient air temperature because of evaporation (but higher with condensation), and that rate of evaporation depends on the mixing ratio.
Surface Tension of Water, Salt and Fresh
Vargaftik et al. (1983) tabulate consensus values for the surface tension of pure water for temperatures between 0°C and the critical temperature
Handbook of Physical Constants Use in Atmospheric Studies
Studies of geophysical boundary layers always require kinematic and thermodynamic constants for the fluids involved. The most obvious examples are for the fluid densities: air, pure water, seawater, and water vapor.
Fluid Mechanics and Machinery
The flow of ideal non-viscous fluids was extensively studied and mathematical theories were developed during the last century. The field of study was called as ‘Hydrodynamics’. However the results of mathematical analysis could not be applied directly to the flow of real fluids.
Siphon Flow Rate Equation and Calculator
Siphon Flow Rate from Small Pipes Equation and Calculator
Siphon Flow and Discharge Rates
Plastic or aluminum smooth wall siphons and tubes are commonly used to deliver water from a canal or ditch to the furrows. These conduits may also be used to measure the rate of flow.
Vacuum Engineering Calculations and Applications
Vacuum is now required for many scientific and industrial purposes, particularly those associated with semiconductors, lighting bulbs, and material-coating industries. The need to manufacture in highly characterized and controlled vacuum brings continual progress in the design, operation, and maintenance of vacuum systems, challenging the people involved in these activities.
