The renal tubules in your kidney are not straight. Rather, they are convoluted and bend around one another. This design allows for liquid to be filtered across a great linear distance of tubule that is packed into a small volume Consider the 1-mm-long segment of distal tubule modeled in Figure 6.64b. The diameter of the distal tubule is 20mm. The velocity of

filtrate entering the segment is 420 cm/min. The specific gravity of the filtrate is assumed to be 1.02. (Specific gravity is defined as the ratio of the density of a fluid to the density of water.) Assuming steady-state conditions, what force must the body exert on this segment of distal tubule to keep it stationary? Report your answer in units of dynes.
