Using the following data, calculate the filtration coefficient for the capillary bed:

Plasma colloid osmotic pressure = 30 mm Hg

Capillary hydrostatic pressure = 40 mm Hg

Interstitial hydrostatic pressure = 5 mm Hg

Interstitial colloid osmotic pressure = 5 mm Hg

Filtration rate = 150 ml/min

Venous hydrostatic pressure = 10 mm Hg
