Water,of density 1000 kg/m³,is flowing in a drainage channel of rectangular cross-section.The width of the channel is 15 m,the depth of the water is 8.0 m and the speed of the flow is .At what rate is water flowing in this channel?

Question

Quizplus · Accepted Answer

The equation for the rate of flow of water is given by:

rate of flow = area of cross-section × velocity × density

The area of cross-section of the channel is:

width × depth = 15 m × 8.0 m = 120 m^2

Substituting the given values in the equation,

rate of flow = 120 m^2 × 11.83 m/s × 1000 kg/m^3

= 1,419,600 kg/s

Rounding off the answer to 1 significant figure gives:

Answer: C) 3.0 × 10^15 kg/s

Therefore, the best choice is C.
