Please give me the complete and correct answer,especially plot the chart and calculate the error,thanks!!

1. A rotameter is to be designed to measure a maximum flow of 12gpm of water at 70F. The bob has a 1 -in diameter and a total volume of 1in3. The bob is constructed so that the density is given in accordance with b=2f. The total length of the rotameter tube is 10 in and the diameter of the tube at inlet is 1.0 in. Determine the tube taper for a drag coefficient of 0.4 . Plot the flow rate versus distance from the entrance of the tube for the drag coefficient. Determine the constant C1 for use in m=2C1yb and estimate the error resulting from the use of this relation instead of the exact expression in Q=Aum=A[Cd1Ab2gVb(fb1)]1/2 (10 points)
