Question

The mass flow rate in a 4.0-m wide, 2.0-m deep channel is 4000 kg/s of water. If the velocity distribution in the channel is linear with depth what is the surface velocity of flow in the channel?

Answer 1

V = 0.5 m/s

Step-by-step explanation:

given data:

width of channel = 4 m

depth of channel = 2 m

mass flow rate = 4000 kg/s = 4 m3/s

we know that mass flow rate is given as

`\dot{m}=\rho AV`

Putting all the value to get the velocity of the flow

`\frac{\dot{m}}{\rho A} = V`

`V = (4000)/(1000*4*2)`

V = 0.5 m/s
