Acapillary viscometer is being used to measure the viscosity of a liquid at 20 c. the capillary tube is 0.01 cm in diameter and has a length of 100 cm. when the pressure drop over the length of this capillary tube was 2 atm, the flow rate of the liquid was found to be 1.0 cm^3 h^-1. what is the viscosity of the liquid in cp? the density of the liquid is 1.025 g cm^3.

Vibration monitoring this technique uses the noise or vibration created by mechanical equipment and in seme cases by plant systems to detemine their actual condtion. a)- true b)- false
