Maintenance work on high-pressure hydraulic systems requires special precautions. a small leak can result in a high-speedjet of hydraulic fluid that can penetrate the skin and cause serious injury (therefore troubleshooters are cautioned to use apiece of paper or cardboard, nota finger, to search for leaks). calculate and plot the jet speed of a leak versus systempressure, for pressures up to 40 mpa gage. explain how a high-speed jet of hydraulic fluid can cause injury.
