You have a series of model D-800 pumps (see attached pump curves) with impeller diameters of 5 to 6 inches and want to determine if any of them can be used to develop at least 10 psi at a flow rate of 100 gpm. Which pump, if any, would you choose (specify pump size, RPM, and impeller diameter)? Explain your choice, and explain why each of the other pumps is not optimal (be specific about why each pump would or would not work)
