Show transcribed image text 5. A capillary viscometer is constructed as shown below. A capilary tube, oriented horizontally is attached to an open reservoir as shown. Liquid flows from the reservoir through the tube and discharges at atmospheric pressure. The amount of liquid flowing through the tube over a given period of time is collected and weighed. The height of the liquid in the reservoir does not change measurably during the experiment. For an unknown liquid whose density is 0.92 g/cm2, 111.8 g are collected over a period of 75s. The height of the liquid in the reservoir is H= 40 cm, the length of the capillary tube is L 25.0 cm, and its inside diameter is 2.0 mm. Evaluate the viscosity of the liquid, and determine if turbulence and entry length effects are negligible. open to atmosphere IH reservoir
