3.21 A manometer is formed from glass tubing with uniform inside diameter, $$D=6.35\mathrm{mm}$$, as shown. The $$U$$-tube is partially filled with water. Then $$K=3.25{\mathrm{cm}}^3$$ of Meriam red oil is added to the left side. Calculate the equilibrium height, $$H$$, when both legs of the U-tube are open to the atmosphere.
