Answer the volumetric flow rate, Q (ft^3/s):

8.17 Benzene flows steadily and continuously at 100F through a 3000 -ft horizontal pipe with a constant diameter of 4 in. The pressure drop across the pipe under these conditions is 300lbf/ft2. Assuming fully developed, laminar, incompressible flow, calculate the volumetric flow rate and average velocity of the fluid in the pipe
