assume the initial guess if cd=0.62

do the calculation for three iterations until the value converges

Example: Given: Methanol at 20C and one atmosphere (methanol=788.4 kg/m3 and =5.857104kg/ms ) flows through a pipe with inner diameter D=4.00cm. An orifice meter with d=3.00cm is installed to measure the volume flow rate. The discharge coefficient matches the typical equation provided above, Cd=0.5959+0.03122.10.1848.0+91.712.5/Re0.75. The two pressure taps are connected to a mercury U-tube manometer (Hg=13,600kg/m3), and the column height difference is h=11.0cm, as sketched to the right. To do: Calculate the volume flow rate in liters per second (L/s).
