PUMPA

Overview

PUMPA is a one-dimensional design and analysis code for pumps. The code was developed by Mr. Joseph Veres at NASA Glenn Research Center. If the overall pump geometry is known, Pumpa can be set up in less than an hour and run on a PC in seconds. Output includes estimates of flow velocities, flow angles, and pressures at the leading and trailing edges, and power requirements.

PUMPA is available to companies and universities within the United States from the NASA GRC software repository:
