View Lower Heating Value Of Natural Gas Kj/Kg US. Lhv = lower heating value of gas (kj/mol). The heating value is usually measured in units of energy per unit mass of the substance, for example, kj/kg, kcal/kg, or btu/m3.
Assuming the efficiency of heating water on a natural gas stove is 65%, determine how much gas would be required to heat 2.0 l of water from 27 to 100˚c?
This is particularly relevant for natural gas, whose. Also referred to as energy or calorific value, heat value is a measure of a fuel's energy density, and is expressed in energy (joules) per specified amount (e.g. Gigatonne of oil equivalent (gtoe). 1 kg of ng is approx.
