In the Oswald viscometer, water flows 25 s from mark line a  

In the Oswald viscometer, water flows 25 s from mark line a to b' while fluid A flows 38 s. The water density at 20 oC and liquid A are 0.9982 and 0.78945 kg dm-3, respectively. Calculate the viscosity of liquid A if the viscosity of water is 1.005 cP !
