The Net glomerular filtration pressure of 55 mm Hg, a plasma protein osmotic force

Given the net glomerular filtration pressure of 55 mm Hg, a plasma protein osmotic force (π_GC) = 12 mm Hg, and a fluid pressure in Bowman’s space (P_BS) = 10 mm Hg, what would be glomerular capillary blood pressure (P_GC)? Would filtration be favored under these conditions? How do you know?

2. An arteriole has a flow rate of 2 cm³/min. Which would increase the flow rate the most, increasing the pressure by a factor of 4, increasing the radius by a factor of 2 or decreasing the viscosity of the blood by a factor of 4? Show calculations.
