Use the Data Below to Calculate the Filtration Coefficient for the Capillary

Use the data below to calculate the filtration coefficient for the capillary bed (in mL/min/mmHg). Plasma colloid osmotic pressure $= 30 \mathrm {~mm} \mathrm { Hg }$
Capillary hydrostatic pressure $= 40 \mathrm {~mm} \mathrm { Hg }$
Interstitial hydrostatic pressure $= 5 \mathrm {~mm} \mathrm { Hg }$
Interstitial colloid osmotic pressure $= 5 \mathrm {~mm} \mathrm { Hg }$
Filtration rate $= 150 \mathrm {~mL} / \mathrm { min }$
Venous hydrostatic pressure $= 10 \mathrm {~mm} \mathrm { Hg }$
