I am using 4 cylinders to raise 2400 pounds. Each cylinder feels 1/4 of the load. I based my pump requirement calculations off of only one cylinder (I figured out what Hp was required to raise the load of one cylinder 1.2in/sec). My reasoning for doing it this way is: If each cylinder requires the same pressure, one pump can deliver it. The 4 cylinders can be configured with one pump and receive the same pressure. So, if P=F/A and P,F,and A are constant for each cylinder it would seem that one pump can do the job. The Hp equation I used only deals with Pressure, GPM, and a .0007 constant. It doesn't consider multiple cylinders. What is the correct way to figure Hp required.

Leading manufacturers are aligning their people, processes, and tools from initial product ideation through to field service. They do so by providing access to product and enterprise data in the context of each personâ€™s domain expertise. However, it can be complicated and costly to unite engineering with the factory and supply chain. Download Now

Itâ€™s easy to fall in love with your own CAD design on the computer screen, but itâ€™s how everything fits together off the screen that really matters. Beyond the design, products need to solve real-life problems or provide huge benefits that genuinely merit separating money from wallets. Download Now
