I have a question hope you respond. I currently have a gauge that reads in PSI and it produces a graph of time VS pressure however I require a reading in lbs kgs or tons is there a way to calculate this.
Hi. great videos and easy to follow (educational videos are usually boring but definitely not yours). I'm an electrical engineer but had trouble following with the mechanical engineers when working together with systems involving hydraulics. I always tried to compare hydraulics to electrical systems ( pressure and flow to voltage and current) but often failed. At this point I think that I was missing that hydraulic pumps are constant flow sources (electrical sources are usually constant voltage) and this is why I couldn't understand the pressure-flow thing. I think by the end of the series I will be able to easily understand and interpret hydraulic circuits. Just want to say that there's a calculation error at 2:03 (650Kpa=94.25psi). Thanks a lot
Pressure Gauges used in Hydraulic Machines have got a small hole of 1 mm dia, How does the gauge shows the correct value of pressure in system, there should be a pressure drop as it is also similar to orifice?

One of the best professor here in RUclips, thank you very much much teaching US.
MAY THE GOD BLESS YOU..
AND GOOD HEALTH ❤️
Many thanks . Your tutorials are very well presented and easy to understand
So awesome i struggled with physics at university and you make it so easy to understand

Good catch! Yes, 650kPa is equivalent to 94.3psi. Good comparison of hydraulics and electronics too.

In the static, no flow condition (ie: no actuators moving nor valves shifting) pressure would be felt equally and undiminished in all directions.
good
