Under this formula, the relationship between the lower heating value of a fuel and the higher heating value of that fuel is: LHV = HHV – 10.55(W + 9H) Where: LHV = lower heating value of fuel in Btu/lb, HHV = higher heating value of fuel in Btu/lb, W = Weight % of moisture in fuel, and H = Weight % of hydrogen in fuel.

We compute the lower heating value (LHV) as the difference in enthalpy (per kg mixture) between reactants and products at constant temperature and pressure, divided by the mass fraction of fuel in the reactants. The LHV is calculated assuming that water remains in the gas phase.

Heating value of gas fuels is measured by Junker's gas calorimeter. Hence, LHV = HHV- m hfg, where m is mass of water formed by combustion (kg) and hfg is latent heat of vaporization of water, kJ/kg.

To calculate the days' supply for insulin, first calculate the total number of units to be dispensed by multiplying the number of units per milliliter by the number of milliliters to be dispensed. Then divide the total number of units to be dispensed by the number of units prescribed per day.

Explanation: Apply the dulong's formula that is: HCV = 1/100[8080C + 34500(H-O/8) + 22400S], here the C, S, O, H are the percentages of carbon, sulphur, oxygen and hydrogen. So, substitute all the given values in the formula and calculate so that you will get HCV.
