Fully filled open water tank has two holes on either sides of its walls. One is a square hole of side x ~cm at a depth of 2 ~m from the top, and the other hole is equilateral triangle of side 4 ~cm at a depth of 6 ~m from the top. If the rate of flow of water is same from both the holes, then ' x ' is

Options

  1. A1.73 cm
  2. B12 cm
  3. C6.92 cm
  4. D3.46 cm

Correct answer

D. 3.46 cm

Step-by-step solution

Volume flow rate, R_v R _ v = area velocity Equating ( i) &(i i) and solving, we get x=2 3 x=3.46 ~cm
