Parameters:

P_osm = osmotic water permeability coefficient

P_salt = salt permeability coefficient

P_urea = urea permeability coefficient

s_salt = Staverman reflection coefficient for salt

s_urea= Staverman reflection coefficient for urea

L = length

D = diameter

C_salt (outside) = concentration of salt in fluid outside of the tubule

C_urea (outside) = concentration of urea in fluid outside of the tubule

K_m = Michaelis constant for salt

J_max = Active salt transport maximum

C_salt(0) = salt (NaCl) concentration at x=0

C_urea(0) = urea concentration at x=0

F_v(0) = axial volume flow rate at x=0
