| @Ashish. Q = AV and 7.2 mld =0. 08334 m^3/sec. Now put the value and get the answer. |

| But how is 7.2 mld equal 0.08334 m^3/sec? | |
| Happy Bansal said: (Oct 12, 2016) | |
| Now find 7.2 mld = 7.2 x 1000/1 x 24 x 60 x 60 = 0.08334 m^3/sec. Q = AV, 0.08334 = 3.14d^2/4 x 1.2. So, 0.08334 x 4/ 1.2 x 3.14 = d = 0.2966 m say 30 cm. |

| Q = 7. 2MLD = 7. 2 * 1000/(24*60*60) = 0. 08334 m3-sec. Then Q=AV; 0. 08334 =3. 14d2/4 *1. 2 d= 0. 2974m, d=29.74 = 30cm. |
