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 2.5 m/s.At what rate is water flowing in this channel? A)2.0 × 10⁵ kg/s B)2.0 × 10³ kg/s C)3.0 × 10⁵ kg/s D)3.0 × 10³ kg/s E)3.0 × 10² kg/s

Question

Quizplus · Accepted Answer

The rate of flow of water can be found using the formula:
rate of flow = cross-sectional area x velocity
The cross-sectional area of the channel can be found by multiplying the width and depth of the channel:
cross-sectional area = 15 m x 8.0 m = 120 m^2
Substituting the given values, we get:
rate of flow = 120 m^2 x 2.5 m/s
rate of flow = 300 kg/s
Therefore, the answer is:
C) 3.0 × 10^15 kg/s
