A mercury (specific gravity = 13.6) manometer connected across an orificemeter fitted in a pipe shows a manometer reading of 2 cms. If the manometer liquid is changed to carbon tetrachloride (specific gravity = 1.6), then for the same flow rate of water the new manometer reading will be _______________ cms?

Question

Accepted Answer

17. The new reading is found by multiplying the original reading by the ratio of the specific gravities (SG_mercury / SG_carbon tetrachloride).
