HYDRAULIC CALCULATIONS 2 exercise 1

Help - Help for Hydraulics Calculations

Exercise # 1

How to use the program.

exercise # 1.

We need to rise a load of 38.000 Lbs. with a hydraulic Glossary Link cylinder, 45 inches up in no more than 18 seconds. This system cannot use more than 2.500 psi of Glossary Link pressure.

 

We need to get the size of the cylinder first, then the Glossary Link flow needed to rise that Glossary Link stroke in that time and the power that has to be used.

 

Exercise # 1

 

These are the formulas that are going to be used to perform the hydraulic calculations.

 

Hydraulic Formulas

 

To get the BORE (in)

 

Get the size of the cylinder (BORE),

knowing P (2.500 psi) and F (38.000 lbs).

 

 

 

 

To get the FLOW (GPM)

 

Get the flow (Q), knowing B (From previous calculation)

and S/t. (45” in 18 seconds)

 

 

 

 

To Get the size of the cylinder (bore) enter the data, then click Calc: 4.4 inches.

 

Find Cylinder Bore dia

 

To get the flow enter the data then click Calc: 9.87357 GPM (gals per minute)

 

Find Flow needed

 

The Theoretical Power needed can be gotten using the following formula. The real Power needed is usually bigger depending on Glossary Link pump’s overall Glossary Link efficiency.

 

To get the theoretical power needed for this application enter data then click Calc:  14.389 HP

 

Find power needed
