Question
Calculate the CV of a fuel sample of coal 0.5 g. Water equivalent of calorimeter 2000g. Increase in temperature =10 °C1 point40 kCal/kg40000 kcal/gm40k kCal/gm40k Cal/gm
Solution
The question seems to be asking for the calculation of the Calorific Value (CV) of a coal sample. However, the information provided is not clear.
In general, the calorific value of a fuel can be calculated using the formula:
CV = Q / m
where:
- CV is the calorific value,
- Q is the heat absorbed (calculated as the product of the water equivalent of the calorimeter and the increase in temperature), and
- m is the mass of the fuel sample.
Given the values:
- Water equivalent of calorimeter = 2000 g,
- Increase in temperature = 10 °C,
- Mass of coal sample = 0.5 g,
we can substitute these into the formula:
Q = 2000 g * 10 °C = 20000 cal
So, CV = 20000 cal / 0.5 g = 40000 cal/g.
However, the units provided in the options are not consistent. The correct unit for calorific value in this context should be cal/g. Therefore, the answer should be 40000 cal/g.
Please clarify the question if this is not what you were asking for.
