A capillary-tube viscometer is being selected to measure

viscosity of a liquid food. The maximum viscosity to be

measured will be 230 cP, and the maximum fl ow rate that can

be measured accurately is 0.015 kg/min. If the tube length is

10 cm and a maximum pressure of 25 Pa can be measured determine the tube diameter to be used. The density of the

product is 1000 kg/m 3 .
