The pressure of wind in pounds per square foot, corresponding to the velocity in miles per hour has been determined by experiment to be approximately as follows: Velocity 20 30 40 50 Pressure 4.4 7.9 13.2 1. This method can be used for interpolation as well as extrapolation. 2. This method should be used when the values of x are equidistant. Estimate the pressure for a velocity of 35 miles per hour?
