    This increased pressure is then matched by the increased delivery pressure (at B) which is developed by the compressor. Now further reducing the flow (to m ˙ C {\displaystyle {\dot {m}}_{C}} and m ˙ S {\displaystyle {\dot {m}}_{S}} ), the increased pressures in the delivery pipe are again matched by the compressor delivery pressures at C and ...

  6. Specific volume - Wikipedia

    en.wikipedia.org/wiki/Specific_volume

    Specific volume is a property of materials, defined as the number of cubic meters occupied by one kilogram of a particular substance. The standard unit is the meter cubed per kilogram (m 3 /kg or m 3 ·kg −1). Sometimes specific volume is expressed in terms of the number of cubic centimeters occupied by one gram of a substance.

    A pressure washer is used to remove old paint from a boat. Patio flagstones being pressure washed using a rotary nozzle. Pressure washing or power washing is the use of high-pressure water spray to remove loose paint, mold, grime, dust, mud, and dirt from surfaces and objects such as buildings, vehicles and concrete surfaces.

    en.wikipedia.org/wiki/Useful_conversions_and...

    Atmospheric pollutant concentrations expressed as mass per unit volume of atmospheric air (e.g., mg/m 3, μg/m 3, etc.) at sea level will decrease with increasing altitude because the atmospheric pressure decreases with increasing altitude. The change of atmospheric pressure with altitude can be obtained from this equation: [2]

  9. Conversion of units - Wikipedia

    en.wikipedia.org/wiki/Conversion_of_units

    For example, the freezing point of water is 0 °C and 32 °F, and a 5 °C change is the same as a 9 °F change. Thus, to convert from units of Fahrenheit to units of Celsius, one subtracts 32 °F (the offset from the point of reference), divides by 9 °F and multiplies by 5 °C (scales by the ratio of units), and adds 0 °C (the offset from the ...
