A loaded flatbottom barge floats in fresh water. The bottom of the barge is 3.76 m below the water line. When the barge is empty the barge's bottom is only 2.89 m below the water line. What is the difference between the pressure on the bottom of the loaded barge and the pressure at the water line? And If the surface area of the bottom of the barge is 220 m^2, what is the weight of the load in the barge? Answer in units of Pa and N. Please show work.
A quantity of air initially at 1 bar, 300K, undergoes two types of interactions: (a) it is brought to a final temparture of 500K adiabatically by a paddle-wheel work transfer, (b) the same temperature rise is brought about by heat transfer from a ..
