Fuel heat-input rate calculator

Fuel mass flow multiplied by heating value gives heat input.

Units
qfuel=mfuel×HVq_{\text{fuel}} = m_{\text{fuel}} \times \mathrm{HV}

Worked example

Given

  • mfuelm_{\text{fuel}} = 500 lb/h
  • HV\mathrm{HV} = 12,000 Btu/lb
qfuel=500×12,000=6,000,000q_{\text{fuel}} = 500 \times 12{,}000 = 6{,}000{,}000
