1.A rectangular section of a river has a discharge of 30m^3 /s where the cr oss section is 12m wide and 1.25 m deep. Downstream, at another cross section , the river is 9m wide and the same depth, but the velocity increases by 10%. Assuming steady, incompressible flow, what is the net change in storage bet ween the cross sections in a 30 minute period of time?

2.Water is weakly compressible but often assumed incompressible; check the validity of this assumption. Using Table 3.1.2 in the text, how much would the volume of 1m^3 of water at 20C change if subjected to the pressure exerted by a 70m column of water?
