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 .
