The radius of an Ostwald viscometer is measured as 168 um. The time of flow of liquid is 19.86 seconds and the volume and pressure of the liquid are 2.864 cc and 0.98 atm respectively. The distance travelled by the liquid during the given time is 2.34 cm. Calculate the viscosity coefficient in cP. * 9.0202 92.5100 9.2051 90.2051 What would be the effect of an increase in the value of the inner radius of the capillary tube to the calculated surface tension of a liquid when all other variables are kept constant? (No calibrating liquid is used.) * The surface tension of the liquid will decrease. The density of the liquid will decrease. The surface tension of the liquid will increase. The density of the liquid will increase.
