Determine the distance by which the mercury will move along the inclined leg of the mercury manometer of the figure below if the pressure in pipe A is decreased by 10 kPa and the pressure in pipe B remains unchanged. The fluid in A has a SG of 0.9, the fluid in B is water and the fluid in between is mercury. SG = 0.9 Water 100 mm 301 80 mm 50 mm Mercury
