During processing, a polymer is pumped through the plant. The pump must produce enough power to move the material a height of 10 meters [m] at a volumetric flowrate of 0.2 cubic meters per second [m³/s]. Assume
the specific gravity of the polymer is 0.6262. If the pump is 75% efficient, what is the power rating on the pump (input power) to supply the necessary potential energy in units of horsepower [hp]?
