To calculate the GCV and NCV of the fuel, we first need to determine the total heat absorbed by the calorimeter. The total heat absorbed (Q) can be calculated using the formula: Q = (mass of water + water equivalent of calorimeter) × specific heat of water × rise in temperature. The specific heat of water is approximately 1 cal/g°C.
