Explanation

 The net pressure gradient that causes the fluid to filter out of the glomeruli into the capsule is 20 mm Hg. A glomerular hydrostatic pressure of 70 mm Hg develops in glomerulus. It is opposed by blood osmotic pressure (30 mm Hg) and capsular hydrostatic pressure (20 mm Hg ) inside the Bowman's capsule.
