2. (14 points) The Cirque du Soleil show KA show in Las Vegas has a massive stage, called the Sand Cliff Deck that is moved by hydraulics (see accompanying article on BB). The following questions are related to the hydraulic system designed to move this stage. a. Pressurized fluid acts against a piston area of 374 in² to lift the 350,000 lb stage and supporting structure. What pressure is required to lift the stage? b. If 2,200 gal/min is needed to lift the stage at 2 ft/s, what fluid power is required? 1 c. If ten Parker PE-145 pumps are used to deliver fluid to the system, what is the total flow rate produced by the ten pumps if the pumps' displacement is 145 cc/rev, they have a volumetric efficiency of 97%, and their shafts are being turned at 1,800 rev/min? 2.
