Determine how much water would be present in a 10 tonne sample of lignite, has a moisture content of 65%, before crushing and drying. 10 tonnes is 10,000 kg.
Wouldn't that be 65% of 10,000 kg?
To determine the amount of water present in a 10-tonne sample of lignite with a moisture content of 65%, follow these steps:
Step 1: Convert the sample weight from tonnes to kilograms.
- 1 tonne = 1000 kilograms
- So, 10 tonnes = 10,000 kilograms
Step 2: Calculate the moisture content of the lignite.
- The moisture content is given as 65%, which means that 65% of the sample weight is water.
- To calculate the amount of water, multiply the weight of the sample by the moisture content as a decimal (65/100).
- Water content = weight of the sample * moisture content
= 10,000 kg * 0.65
= 6500 kg
Therefore, the 10-tonne sample of lignite with a moisture content of 65% would contain 6500 kilograms (or 6.5 tonnes) of water before crushing and drying.
