The flow rate f in m3/s of water through a particular pipe, as a function of the pressure drop p across the ends of the pipe (in N/m2) is given by f = 0.002√p. Obtain a linear model of f as a function of p that always underestimates the flow rate over the range 0 ≤ p ≤ 900.
In the following problems for Section 1.4, plot the data on suitable axes, and solve the problem by drawing a straight line by eye using a straightedge.
