H&P UNIT TEST 1 QP

This document contains an exam for a Hydraulics and Pneumatics course. It has two parts: Part A contains 10 multiple choice questions testing students' knowledge of fluid power systems, types of pumps, hydraulic fluids, and pump performance parameters. Part B contains 3 longer answer questions asking students to explain gear pumps, applications of fluid power systems with examples of merits and demerits, and performing calculations related to pump flow rate, power, and torque given pump specifications and efficiency. The exam aims to assess students' understanding of key concepts related to pumps and hydraulic systems.
