Louse's Export and Café (Louse's E&C) decides it wants to ship Ponderosa pine lumber from Washington State to Southern China for manufacturing into furniture parts.
They know that a container will physically hold about 80 cubic meters of wood, but they will be billed based on weight, so they want to estimate the weight of the average container load.
Naturally, they hire a BBE 1002 intern to solve this problem for them! The factory Louse's E&C will buy the lumber from tells them the average dry basis moisture content at time of shipment is 15.0%.
From the Wood Handbook the intern learns that the Specific Gravity of Ponderosa pine at 12% is 0.40 (which is close enough for use in your calculations). Also, she determines from the Internet the Specific Gravity of water is 1000 kg/cubic meter.
Q#1: About How Much Will The Container Load Of Wood Weigh (Excluding The Weight Of The Container Itself)?
Q#2: What Is The Weight Of The Water In This Container Load Of Ponderosa Pine?
Q#3: If The Cost To Ship Is $100 Per Metric Ton (1000kg), How Much Does The Water Portion Of The Load Cost To Ship?
