A canal has rectangular cross section of width 10cm and breadth 1m. If water of uniform density 1 gm cm-3 flows through it at a constant speed of 1000mm per minute, the adjacent sea is
100000
1000000
120000
30000
350000
Correct answer is A
The canal's width = 10cm = 100mm (given) The speed of water = 1000mm 10mm = 1cm 1000mm = 100cm The adjacent sea must give speed x width = 1000 x 100 = 100,000
