Afferent Arteriole Pressure Formula

Equation for calculate afferent arteriole pressure is,

P_a = (R_a x Q_a) + P_G

where,
R_a = the afferent arteriole resistance,
Q_a = the afferent arteriole flux,
P_G = the hydrostatic pressure within the glomerular capillaries,
P_a = the afferent arteriole pressure.
