Unformatted text preview: Date: 19 May 2010 To: Dr. Mark Zohns From: Roman Ferro Subject: Lab Activity 7 Motor Displacement Exercise: Bail Out Steering System A. Motor Displacements Bore - 2.25in Rod - 1.5in Stroke – 3.625in B. Volume Displaces per Revolution Total steering wheel revolutions – 4.25 Total Displacement This motor is the 1.93in^3/rev, because this motor is the has the closest displacement per revolution to that which we calculated. Test Stand: Parallel Circuit Flow Rate- 2.5gpm P1 ∆P P2 No Load 600 400 200 Load on B 700 500 200 As a load is applied on one of the motors, a pressure drop will occur across that motor and the flow rate to that motor will decrease along with the rpm of that motor. As the amount of fluid flowing to the motor under a load decreases, the fluid will flow more easily to the second motor, increasing the rpm of that motor. The flow rate remains constant during this entire process. increasing the rpm of that motor....
