Pump Efficiency Data Analysis

The document records observations from experiments conducted using a two-stage pump. It lists measurements taken at different pressure gauge readings and vacuum levels, including head, time for the energy meter to register two revolutions and 100mm of rise, discharge rate, input and output power, and efficiency. On average, the pump achieved an efficiency of 27.26% across five trials.
