Using a hand pump, pressure of 100 PSI has been built up in a hydraulic system. The hand pump piston is 1 inch in diameter. A 1/2-inch line connects the hand pump to an actuating cylinder 2 inches in diameter. What is the pressure in the line between the hand pump and the actuator? - ️️100 PSI. A common cause of slow actuation of hydraulic components is - ️️internal leakage in the actuating unit. In a hydraulic system that has a reservoir pressurized with turbine-engine compressor ...
