# A large water pump is being designed for a nuclear reactor. The pump should deliver 2500

Fluid Mechanics Fundamentals and Applications | 3rd Edition

A large water pump is being designed for a nuclear reactor. The pump should deliver 2500 gpm of water at a net head of 45 ft at its best efficiency point. A motor that spins at 300 rpm is available. What kind of pump (centrifugal, mixed, or axial) should be designed? Show all your calculations and justify your choice. Estimate the maximum pump efficiency that can be hoped for with this pump. Estimate the power (brake horsepower) required to run the pump.

EM 274 - Statics Jan. 8th, 2018 Force: Pushing, Pulling, or Rubbing, wants to cause motion in a straight line (translational motion) Moment: Wants to cause motion about a point (rotational/spinning motion) *Forces and moments applied together prevent rotating Steps of solving force problems: 1. Before even starting the problem, draw what’s going on! a. Free-Body Diagrams: shows all forces, moments 2. Write equilibrium equations 3. Solve system of equations *Pay attention to: - Units and unit conversions (both SI units and English units) - Significant figures and rounding (scientific notation) * Carry your significant figures all the way through your
