Due to rise in temperature, the viscosity and unit weight of percolating fluid are reduced to 70% and 90% respectively. Other things being constant, the change in coefficient of permeability will be-A-20.0%B-28.6%C-63.0%D-77.8%-B-28.6%

Question

APTITUDE CRACK · Accepted Answer

B 28.6% Taylor&#39;s equation based on Poiseuille&#39;s law for laminar flow through the circular tube is given by k=r&Icirc;&frac14;e31+ec2D Change in the coefficient of permeability. k1 = 0.9r0.7&Icirc;&frac14;e31 + ecD2. k1k = 0.90.7 * 100 = 128.57%. change = 28.57%.
