  2. Pound per square inch - Wikipedia

    en.wikipedia.org/wiki/Pound_per_square_inch

    The kilopound per square inch (ksi) is a scaled unit derived from psi, equivalent to a thousand psi (1000 lbf/in 2). ksi are not widely used for gas pressures. They are mostly used in materials science, where the tensile strength of a material is measured as a large number of psi. [4] The conversion in SI units is 1 ksi = 6.895 MPa, or 1 MPa ...

  4. Pressure - Wikipedia

    en.wikipedia.org/wiki/Pressure

    Other units of pressure, such as pounds per square inch (lbf/in 2) and bar, are also in common use. The CGS unit of pressure is the barye (Ba), equal to 1 dyn·cm −2 , or 0.1 Pa. Pressure is sometimes expressed in grams-force or kilograms-force per square centimetre ("g/cm 2 " or "kg/cm 2 ") and the like without properly identifying the force ...

    en.wikipedia.org/wiki/Talk:Pound_per_square_inch

    The difference seems to arise from an ambiguity in the definition of the pound-force. I was to taking this to be 1 lbf = 4.4482 N (the value stated by IEEE 260.1), while you are using the product of 1 lb with the international standard accelration due to gravity (g_std), resulting in a different value for lbf and therefore also for lbf/in^2.

    The fourth category of furnace is the high-efficiency condensing gas furnace. High efficiency condensing gas furnaces typically achieve between 90% and 98% AFUE. [3] A condensing gas furnace includes a sealed combustion area, combustion draft inducer and a secondary heat exchanger. The primary gain in efficiency for a condensing gas furnace, as ...
