A piston, D=50mm, sits on top of a fluid (S.G.=11) connected to a 10mm diameter tube, open to the atmosphere. a) if the fluid height above the piston bottom is 20mm with no external force (F=0) to what height will it rise when an external force of 50 N is applied? b) How much higher could the fluid rise if capillary action is included. Surface Tension=.5 N/m and contact angle, theta=0.
