What Happens To Flow Rate As Diameter Decreases?

What Happens To Flow Rate As Diameter Decreases? Bernoulli’s equation states mathematically that if a fluid is flowing through a tube and the tube diameter decreases, then the velocity of the fluid increases, the pressure decreases, and the mass flow (and therefore volumetric flow) remains constant so long as the air density is constant.

How Does Gradient Change Discharge?

How Does Gradient Change Discharge? Discharge increases, as noted above, because water is added to the stream from tributary streams and groundwater. As discharge increases, the width, depth, and average velocity of the stream increase. The gradient of the stream, however, will decrease. How does the gradient of a river change from headwaters to mouth?
