is the answer 3.575 ft or 1.2165 ft? Please help
The two pipes shown contain hexylene glycol, which causes the differential pressure reading of the mercury manometer, i.e., the manometer deflection,to be initially h=1.2ft.The pressure in pipe A is then increased_by 0.75psi and the pressure in pipe B reduced by 0.2 psi. What is the resulting manometer deflection after the changes in pressures in the pipe? The specific gravity of hexylene glycol may be taken to be 0.923 and that of mercury to be 13.55.
Hint: Working with piezometric heads may be advantageous
