Water is flowing through two horizontal pipes of different diameters which are connected together. The diameters of the two pipes are 3 cm and 6 cm respectively. If the speed of water in the narrower tube is `4 ms^(-1)`. Then the speed of water in the wider tube isA. `16 ms^(-1)`B. `1 m s^(-1)`C. `4 m s^(-1)`D. `2 m s^(-1)` |

Answer» Correct Answer - B From continutiy equation `v prop 1/A" or v "prop1/d^(2)` (d = diameter of pipe) `v_("narrow")/v_("Wider")d_(w)/d_(N)=(6/3)=rrArrv_("Wider")=v_("narrow")/4=4/4=1 ms^(-1)` |
