If the heat of combustion of the wood is 9.8 MJ kg-1 and the power station will generate electricity with an efficiency of 31% when burning wood, calculate how much electricity can be produced (in units of MW) if the station burns 10 tonnes of wood per hour. Give your final answer to 1 decimal place. How much wood would need to be burned per hour to maintain an output of 500 MW from the power? Give your answer to 2 significant figures. The wood is to be stored under cover and the plant operators wish to keep two weeks supply of wood on site. If the bulk density of the wood is 300 kg m-3, calculate the minimum volume of storage that will be required for the 500 MW
