1.How many mg/L of magnesium ion will remain in solution of water that is .001 M in hydroxyl ion and at 25 degree Celsius?
2.What pressure gradient along the streamline, dp.ds is required to accelerate water upward in a vertical pipe at a rate of 10 m/s2
3.A grit chamber is designed for a flow-through velocity of 0.30 m/s, a depth of 0.9 m, and a length of 10.5 m. If inorganic particles have a specific gravity of 2.65, estimate the diameter of the largest particle that can be removed 100% at 20 degrees C.
4.How do you get the equations for the elastic curve using x1 an x2 coordinates?
