An unknown fluid flows through a horizontal 35-mm-diameter pipe with a Reynolds number of 100,000 and a density of 680 kg/m3. The pressure drop across a 21-mm-diameter nozzle meter placed in the pipe is 4.2 kPa.
(a) Determine the discharge coefficient for the nozzle meter.
(b) Determine the dynamic viscosity of this fluid (N-s/m).
