When filtrate flow through the renal tubule increases, reabsorption of sodium chloride by the tubule.

When filtrate flow through the renal tubule increases, reabsorption of sodium chloride by the tubule increases.

Increased flow of tubular fluid have the same effect as increased sodium chloride (salt) concentration, on the process of renal reabsorption. This is the part of tubuloglomerular feedback which is the mechanism that kidney uses to regulate glomerular filtration rate.
