    Energy content of gas calculation

    Thanks Pablo; as this gas is for use in IC engines, we're interested in the LHV, but I assume we will be able to get both once the gas analysis is completed. The gas isn't being supplied; we are generating our own low-BTU gas from municipal solid waste and we wish to determine the actual energy...

    Energy content of gas calculation

    We have the volumetric capacity and speed of the engine to calculate flowrate; as for engine efficiency, a standard assumption for efficiency would be sufficient for this calculation. We are doing a compositional analysis, but for the time being we would like to have a rough estimate of the...

    Energy content of gas calculation

    I'd like to know how to calculate the energy content in BTU/cubic feet of a gas if we are burning it in an engine to produce a known output of power (13 kW) at 1400 rpm.

    Shaft deflection in API 610 7th Edition

    I am looking for the maximum allowable shaft deflection under API 610 7th Edition. I understand that this is given for the shaft at the impeller, as opposed to 8th Edition which states a maximum deflection of 0.002 in. at the mechanical seals.
