A liquid of density 10 kg /m^3 and coefficient of viscosity 8 * 10^(-2) decapoise is flowing in a tube of radius 2 cm, with a speed of 2 m/s. The Reynold's number is 1000 (2).
1) Given, coefficient of viscosity is 8 * 10^ (-2) decapoise = 8 * 10^(-3) poise =8 * 10^( -4 ) N-s/ m^2.
2) Reynold's number is given by = (rho) * v * d / (mew)
3) So, Re = (10 * 2* 0.04) / (8 * 10 ^(-4)) = 1000
