Condensed water

The following observations were taken during a test to determine the calorific value of a gaseous fuel using a Boy's calorimeter:

$,$ volume of gas consumed $=14$ litres

gas pressure $=25mm{H}_{2}O$

gas temperature $=19C$

atmospheric pressure $=104,121Pa$

Cooling water collected $=2\mathrm{.}3kg$

Cooling water inlet temperature $=13\mathrm{.}5C$

Cooling water outlet temperature $=36\mathrm{.}6C$

condensate collected $=5\mathrm{.}15g$

Calculate:

a$.$ the higher or Gross calorific value of the fuel per cubic metre at NTP

b$.$ the lower or Net calorific value of the fuel per cubic metre at NTP

Data:

Specific heat capacity of water is $4,187Jk{g}^{-1}{K}^{-1}$

Specific latent heat of vaporisation of the condensate at NTP can be taken to be $2,453KJk{g}^{-1}{K}^{-1}$

Normal temperature and pressure $($NTP$)$ is $15C$ and $101,325Pa$

Density of water is $1,000kg{m}^{-3}$
