(a) Water at a temperature of 20°C
Equations and Assumptions:
(1) From Table A.5, Pv = 2340 N/m2 abs
Cavitation (boiling) of water occurs when the local pressure drops below the vapor pressure;
therefore, a pressure at or below 2340 N/m2 abs would cause the water to boil.
When the pressure drops below the vapor pressure, bubbles will begin forming as part of
the cavitation process. Problem: As shown, a mouse can use the mechanical advantage provided by a hydraulic
machine to lift up an elephant.
(a) Derive an algebraic equation that gives the mechanical advantage of the hydraulic
