For devices equipped with a barometer, this application uses the Atmospheric Pressure measured by your phone to calculate the Sea Level Adjusted Barometric Pressure at your location. Temperature and Altitude, also used in the calculation, are obtained by matching your position against weather and altitude survey databases. These values are more reliable than the values returned from your GPS chip and your phone's temperature sensor and may result in a more meaningful barometric pressure reading.
Devices without a barometric pressure sensor will show the barometric pressure at your location by using your GPS and internet connection.
★ Now includes an option that allows the application to perform behind-the-scenes atmospheric pressure monitoring with a visual representation of the pressure trends as a line graph.
★ "DS Barometer. Reliable: Works Great Under Pressure!"
Altimeter and thermometer included.
Simply input your pressure value and select the To and From Pressure measurement and the Pressure Converter will automatically display the result for you.
The Pressure Converter is ideal for plant, process and service engineers, site contractors and laboratory technicians in oil & gas, power generation and other industrial settings, where basic conversion may be needed but a computer is not always easily accessible.
The Pressure Converter currently supports the following measurement conversions:
bar, psi, mbar, N/m², Pa, hPa,
kPa, MPa, kgf/cm², mmH2O 4°C, cmH2O 4°C,
mH2O 4°C, inH2O 4°C, ftH2O 4°C, mmHg 0°,

“The Pressure Converter application lets our customers quickly and easily access our pressure unit conversion tool when they are in the field,” said Graham Dawber, Leader of the pressure product line at GE Sensing. “This is the first in a number of free applications we are developing to help our customer’s access useful information through their mobile device.”

The total pressure loss in the system results from the combined losses due to friction in length of pipe and friction losses due to valves, fittings, and other components. The first are "major losses" associated with energy loss per length of pipe, and seconds are "minor losses" associated with bends, fittings, valves, etc.
The factors that determine friction losses in pipe are:
The velocity of the water: As velocity increases, pressure losses increase. Velocity is directly related to flow rate.
The size (inside diameter) of the pipe: Smaller pipe causes a greater proportion of the water to be in contact with the pipe, which creates friction. Pipe size also affects velocity. Given a constant flow rate, decreasing pipe size increases the water’s velocity, which increases friction.
The roughness of the inside of the pipe: Pipe inside wall roughness is rated by a C factor, which can be selected depending on material of pipe. The lower the C value, the rougher the inside and the more pressure loss due to friction.
The length of the pipe: The friction losses are cumulative as the water travels through the length of pipe. The greater the distance, the greater the friction losses will be.
The friction losses for, elbows, and tees can also be selected. The friction losses in fittings such as couplings, elbows, tees, valves and other elements play a role. Friction loss from these components must be taken into account when calculating friction losses for each section of pipe.
Calculation of friction factor is based on the Hazen-Williams equation. Local resistances factor K for valves and some fittings (tees, elbows, pipes contraction and enlargement), can be found in app itself.
Calculate pressure losses in a pumping of 10 l / s. The diameter of the suction and discharge is 100 mm or 4 ". We have the following items on the Suction: 1 foot valve, 1 gate valve , 1 elbow 90, 1 contraction to 3" to entering the pump. In the discharge we have: 1 expansion, 2 elbow 90,
a check valve, 1 gate valve. The total pipe length is 10 meters in diameter of 100 mm. Must be calculated the pressure losses for the given flow.
NOT FOR NAVIGATION
A bare bones pressure altimeter just like the one in an airplane (except red, for some reason). There are no additional features: if an airplane altimeter doesn't do it, this app won't do it. Unless you count "being red" as a feature.
Uses the pressure sensor in your Android device and the altimeter setting you provide to estimate your altitude. Don't have a pressure sensor? In that case, it pretends you're at sea level. Just to make it clear: this app won't show your altitude unless your device has a pressure sensor inside.
New to altimetry? Check Wikipedia to learn more about altimeter settings (http://en.wikipedia.org/wiki/Altimeter). Then check your nearest, most recent METAR (http://en.wikipedia.org/wiki/METAR) to learn the correct altimeter setting for your area.
Use the volume buttons to change your altimeter setting.

LAB-EL HUMIDITY CALCULATOR computer program calculates uncertainty results. These are taken from uncertainty of input data (introduced by the user through the input window) and the uncertainty of formula used for moisture calculation.
The results are true with respect to over water or to over ice, depending on whether there is water or frost (ice) in the chilled mirror hygrometer or psychrometer.
The input and counted data values are as follow:
DP - dew point temperature,
FP - frost point temperature,
RH - relative humidity with respect to water (or to ice),
T - air temperature,
Tw/Ti - the wet-bulb (or ice-bulb) temperature in psychrometer,
P1 - air pressure at point 1, where input values are defined,
P2 - air pressure at point 2, where values are calculated,
PPMV - volume of water vapour in dry air (ppm, parts per million),
PPMW - mixing ratio, weight of water vapour in dry air (ppm, parts per million),
x - mixing ratio, weight of water vapour in dry air (g/kg),
I - enthalpy I(1+x) of mixture dry air (1) and water vapour (x),
WVP - vapour pressure in moist air,
SWVP - saturation vapour pressure of moist air with respect to water (or to ice).
