The Free Hydraulic Calculator includes many basic hydraulic calculations.
Cylinder calculations can be done to solve for extension / retraction forces or speeds.
Pump calculations can also be done by entering combinations of displacement, oil flow and pressure to determine values for speed, torque and power. Both mechanical and volumetric efficiencies can be used in these calculations.
Hydraulic line calculations can also be done for fluid velocity, cross sectional area, Reynolds number and pressure drop. The free version is limited to 1” or 25mm line diameters.
Orifice calculations can also be made using three parameters: Oil Flow, Orifice Diameter and Pressure Drop. Enter any two values and have the third calculated.
Speed - Torque - Power page: Enter any two values have the third calculated. Unit conversions built into the page.
Calculations can be done in either metric or imperial units. Basic unit conversions are also available.
With the in-app purchase, all features from the Hydraulic Calculator will become active:
Cylinder characteristics can be entered in a number of different ways. Enter hydraulic flow, cylinder velocity, or stroke time and calculate the other two. User can also enter Hydraulic pressure, extend force or retract force and have the other two calculated.
One application for this is to measure the stroke time of a cylinder. By entering this with the bore diameter and stroke length, the system flow is calculated.
Full motor & pump calculation page. The motor & pump calculator are flexible tools in which the user can enter any three known values to have the remaining values calculated. Values include: displacement, oil flow, pressure, rotational speed, torque, and motor power. Both mechanical and volumetric efficiency values are used.
Results can be copied to the clipboard in a text format for use in e-mails, messages, or other documentation.

Handy App - 1 Suggestion
Nice app, easy to use and pretty comprehensive. One suggestion would be to allow the user to switch units on the fly. Essentially, either while inputting the value or reading the result the user could simply tap and change the units. For example tap the units for pressure and change from psi to bar. I regularly work with vendors overseas and customers in the US. Conference calls are fun when the vendor tells me the the displacement in ccm and the customer is telling me the pressure in PSI and everyone is asking about the motor’s torque output. Of course they want the answer in ft-lbs and Nm.
I've had this app for about 2 or 3 years and I use it several times a week in the course of my job.
I do functional integration of industrial hydraulic systems. Being able to quickly calculate the required HP for a system is invaluable when you're running a new and untested system (contrary to beliefs, engineers constantly fail to do this when specs are made and a unit will be underpowered or over worked).
I also have two other hydraulic apps from these guys and I guarantee you'll love them if you're around hydraulics and need quick calculations.
Can't recommend them highly enough and I've even had my company's monthly newsletter include screenshots and info regarding these apps so all the employees are aware of how useful they are in our profession.
