A canal has rectangular cross section of width10cm and breadth 1m. If water of uniform density 1 gm cm-3 flows through it at a constant speed of1000mm per minute, the adjacent sea is
-
A.
100000 -
B.
1000000 -
C.
120000 -
D.
30000 -
E.
350000
Correct Answer: Option A
Explanation
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
