Chesterfield currently uses 11,400 m³/d (average flow) of water which is drawn from a storage reservoir. Historically, the minimum flow (i.e., winter) used on a daily basis is 25% of the average. The peak daily flow (i.e., summer) is 230% of average. The intake for the treatment plant is located in a tower and it is desired to have a velocity of 0.15 m/s through the inlet port under average conditions. What is the required open area (in m²) of the inlet port under average flow conditions? b. What is the velocity of water through the port under minimum and maximum flow conditions? If the area is susceptible to freezing conditions in the winter, would ice formation on the inlet port be a concern? Justify your response quantitatively. d. What would be the maximum winter flow that could be obtained using the port size obtained in part (a) above? а. с.

In mixing tanks systems, the water comes in at a rate of 4L/min in Tank A. This tank contains 500L solution of brine with 200g of salt is dissolved. The solution is then pumped to Tanks B and C, at 2L/min and X L/min, respectively. Tank B has 400L solution of brine and 1000g dissolved salt. It is then pumped to Tank C with a rate of 4L/min. Tank C has only 400L of plain water only and pumps it back to Tank B at a rate of y L/min. Moreover, z L/min exits the system of Tank C. Considering that the volume of the solutions are constant all throughout, solve for the values of x, y, z
