Finding the nozzle pressure of antifreeze used to de-ice a plane.
Using a Radical ModelYou work for a commercial airline and remove ice from planes. The relationshipamong the flow rate r (in gallons per minute) of the antifreeze for de-icing, thenozzle diameter d (in inches), and the nozzle pressure P (in pounds per squareinch) is shown in the diagram. You want a flow rate of 250 gallons per minute.
