For each location you want to record air volume, simply enter the average velocity pressure (from your pitot tube readings) and the pipe dimension(s). The app can handle circular pipes or ducts. The calculated results display both the air velocity in feet per minute (FPM) and the air volu...
To calculate the kinematic viscosity of air at pressure 1 bar (105 Pa) and 50 °C, enter a few details into the kinematic viscosity of air calculator: Convert the temperature in Celsius to kelvin: T = 273.15 K + 50 = 323.15 K. Calculate the density of the air from the ideal gas law...
Free Fall with Air Resistance Calculator determines the time of fall, maximum or terminal velocity provided the inputs as per the input section. Give inputs and check how quickly our calculator does work for you.
v2= Velocity of escaping air in feet per second (ft/sec); g = Acceleration due to gravity, 32.16 feet per second squared (32.16 ft/sec2); k = 1.41 for adiabatic expansion or compression of air; F = Temperature, degrees F; p2= Atmospheric pressure = 14.7 pounds per square inch (14.7...
Flow of Air in Pipes Equation and Calculator where: v = velocity of air in feet per second (ft/sec) p = loss of pressure due to flow through the pipes in ounces per square inch (ounces/in2) d = inside diameter of pipe in inches (in) ...
The Dwyer Air Velocity and Flow Calculator makes spot checking with Dwyer Pitot Tubes quick and easy. Calculates air velocity and flow from a variety of inputs,…
Negative Air Machines with higher velocity ratings are generally more adept at handling larger volumes of air. Assess the machine’s filtration efficiency, ensuring it features a High-Efficiency Particulate Air (HEPA) filter and potentially activated carbon filters for comprehensive contaminant removal.Buy...
