Capillary viscometer.You have already measured the density of an unknown fluid and found it to be 1.35 g/ml. You wish to determine the fluid viscosity from measurement of the pressure drop through a 1 mm ID by 1 m long capillary as a function of the flow rate. For a flow rate of 45 ml/min, you find the pressure drop to be.Which of the following is the best estimate of the fluid viscosity?

MCQs on how fluids (gases and liquids and a few other materials) respond to forces, exert forces, and move from one place to another (their mechanics).
